First HF Station Build: 100 Watts, a Wire Antenna and a Real Ground

This is the build most people should aim at, and the one where nearly every line item is still correct ten years later. A hundred watts, a wire antenna that covers eight bands from a single support, a tuner that makes the compromises invisible, and a grounding system that is on the list because it is a safety requirement rather than an upgrade.

The required items total about $2,017. The distribution of that money is the useful part: the radio is 38 percent, matching and measurement is 23 percent, and the antenna itself is $90. If that ratio looks wrong, it is not. On HF the antenna is the cheapest major component and the largest single determinant of whether anyone answers you.

Grouped by function, because the groups are how you stage the purchase. The grounding group is the one people defer and the one they should not.

First HF station, General class

Item	What it does	Qty	Price
The radio and its power A 100 W HF radio draws 22 amps. Nothing else in the station comes close.
Yaesu FT-891 100 W on every HF band plus 6 m, all modes, in a detachable-head chassis that works on a desk or in a vehicle. No internal tuner, which is why the tuner is a separate line.	HF transceiver	1	$769.95
Powerwerx SS-30DV desktop power supply Switching supply with Powerpole outputs and adjustable voltage. Thirty amps against a 22 A peak draw is the right headroom; a 20 A supply will sag on SSB peaks and the radio will fold back.	30 A power supply	1	$164.17
Powerwerx PD-5F fused distribution block Five individually fused outputs from one supply feed. Individual fusing is what stops one accessory fault taking the whole station down mid-net.	Fused DC distribution	1	$50.85
30 A quick-disconnect power connectors, 40-piece Standardise every DC connection in the station on one housing. Forty pieces is enough for the whole build plus spares.	DC connectors	1	$9.99
The antenna One wire, one support, eight bands. The highest-value part of this build.
JYR8010 8-band end fed half wave, 150 W A 49:1 transformer feeding a single wire, resonant enough on eight bands to work without a tuner on most of them. Needs one high support and a feedpoint at ground level, which is why it suits a normal lot when a dipole does not.	End fed half wave, 80 to 10 m	1	$89.99
QNR 3/16 in polyester antenna rope, 500 ft Polyester, low stretch, UV resistant. The spool is cheaper than buying rope three times, and you will put up more than one antenna.	Support rope, 500 ft	1	$49.73
Forester arborist throw line kit Fifteen ounce weight on 166 ft of slick line. This is how you get a rope over a branch fifty feet up from the ground, and it is the correct answer instead of a ladder.	Line launcher	1	$21.99
Nylon dog bone antenna insulators, 10-pack Ten nylon insulators, four antennas worth. Nylon does not shatter in cold the way ceramic can.	End insulators	1	$29.97
FT-240-31 ferrite toroid core Twelve turns of coax on a type 31 core at the feedpoint gives several thousand ohms of choking impedance across 3.5 to 14 MHz. Without it the feedline becomes part of the antenna and RF ends up in the shack.	Common-mode choke core	2	$23.34
Feedline Buy the coax once and buy it right.
MOOKEERF RG-213 coax, 100 ft with UHF male RG-213 loses 0.6 dB per 100 ft at 7 MHz and handles legal-limit power, so it is still correct if you later add an amplifier. Solid dielectric tolerates being walked on.	Coax, 100 ft	1	$115.99
PL-259 solder connectors with reducers, 6-pack Six PL-259 plugs with reducers for every common cable size. Buy more than you need; the first three are practice.	Spare connectors	1	$9.99
Self-amalgamating rubber splicing tape Rubber splicing tape as the first layer over every outdoor connection.	Weatherproofing	1	$9.99
Hand-moldable sealant tape Packs into the gap at the connector body, under the rubber tape.	Connector sealing	1	$9.69
UV-resistant heavy duty zip ties, 100-pack UV stabilised. The natural-coloured ones fail in a single summer.	Cable dressing	1	$6.99
Matching and measurement A wire antenna on eight bands needs a tuner and an honest meter.
LDG Z-11ProII automatic antenna tuner 1.8 to 54 MHz, 125 W, with 2000 memories so a band change retunes in under a second. The FT-891 has no internal tuner, so this is not optional on a multiband wire.	Automatic antenna tuner	1	$225.44
Daiwa CN-501H cross-needle SWR and power meter Cross-needle 1.8 to 150 MHz meter showing forward, reflected and SWR at once. A cross-needle display shows a changing match faster than any digital readout.	SWR and power meter	1	$151.99
NanoVNA H4 vector network analyzer Sweeps the antenna and shows you where resonance actually is, which an in-line meter cannot. Under $100 for a measurement that used to cost thousands.	Antenna analyzer	1	$89.90
XRDS-RF 100 W dummy load, 50 ohm Optional Lets you check power output and verify the meter without radiating. The correct way to test a transmitter.	Dummy load	1	$45.49
Grounding and lightning protection Not optional once there is a permanent outdoor antenna. This is a safety system.
8 ft copper-bonded ground rod kit with clamp 8 ft copper-bonded rod with clamp, at the point where coax enters the building. Must be bonded back to the house electrical service ground, not left isolated.	Ground electrode	1	$54.80
Proxicast ProGrade coaxial lightning arrester, SO-239 Gas-tube arrester at the entry point, bonded to the rod. An arrester not bonded to an outdoor electrode does nothing.	Coaxial arrester	1	$19.95
Max-Gain Systems bulkhead SO-239 feedthrough The proper place to land the coax, bond the shield and mount the arrester rather than running cable through a window.	Entry bulkhead	1	$35.00
Copper grounding bus bar kit, 16 positions Single-point ground bar behind the desk. One bar, one path, no loops.	Station ground bar	1	$21.50
Tinned copper ground strap braid, 15 ft Flat tinned braid has lower RF inductance than round wire of the same weight, which is why bonding straps are flat.	Bonding strap, 15 ft	1	$22.99

Why a hundred watts and not less

A hundred watts is the standard HF power level, and the reason is not that more is better. It is that the whole ecosystem is built around it. Antennas are rated for it, tuners handle it, and every band plan and net practice assumes it. Going below it is a deliberate choice with real consequences, and going above it is a separate project.

One S unit is 6 dB by convention, which means going from 100 W to the legal limit is two S units. Raising a dipole from a quarter wavelength to a half wavelength above ground can gain more than that on a DX path, for the price of some rope. This is the arithmetic that explains why experienced operators talk about antennas and height rather than about amplifiers, and why the amplifier lives in the next build up rather than this one.

What the tuner is actually for

An antenna tuner does not tune your antenna. It presents a 50 ohm load to your radio by transforming whatever impedance appears at the end of the feedline. The antenna out in the yard is unchanged, and so is any loss in the feedline.

That matters because a tuner can happily show 1 to 1 at the radio while the antenna is badly mismatched and the coax is heating up. On this build, with an end fed half wave that is close to resonant on most bands, the tuner is doing a small job: cleaning up a 2.5 to 1 match into a 1.2 to 1 one, with a fraction of a dB lost in the process. That is exactly the case a tuner is good at. The case it is bad at is a badly non-resonant antenna on a long coax run, where the extra loss from the high standing wave in the feedline is real and the tuner hides it from you. Read antenna tuner basics for the full picture and tuner versus resonant antenna for when to stop reaching for one.

Feedline: why RG-213 and not RG-8X

At HF frequencies both are acceptable, so the reasoning is about the future rather than the present. Here is the actual difference over the 100 foot run in this build.

On 7 MHz the difference between RG-8X and RG-213 is 0.4 dB, which nobody can hear. The reason to buy RG-213 anyway is the power rating column. If you ever add the 600 W amplifier from the next build, RG-8X becomes marginal and you buy the coax a second time, including pulling it back out of whatever conduit or wall it now runs through. Buying it once at the higher rating costs about $66 more and saves the whole job.

LMR-400 is lower loss still and is the right answer if this run also has to serve a 2 m antenna later, where its 1.6 dB against RG-213's 3.1 dB at 144 MHz is a real difference. It is stiffer and less tolerant of tight bends. Compare all three properly on RG-8X versus RG-213 versus LMR-400, and put your own run length into the coax loss calculator.

What you can safely skip at this tier

• An amplifier. Two S units for over a thousand dollars, plus a harder RF exposure evaluation, plus a bigger power supply. It belongs after the antenna is as good as your lot allows, not before.
• A second antenna, at first. Get the end fed working across all eight bands and learn what it does badly. That tells you which second antenna to build, which is usually a 40 m dipole or a vertical for the low bands.
• A linear power supply. The $551 Astron RS-35M-AP linear power supply is genuinely quieter on the bands than any switcher, and it is a luxury at this tier. A modern switching supply with a noise-offset control solves almost all of it for a third of the price. See linear versus switching.
• A rotator and a beam. A wire antenna and a rotatable beam are different projects. The beam needs a mast, a rotator, rotator cable, a tower or a strong roof mount, and an engineering conversation about wind load. That is the next build.
• A desk microphone. The hand microphone that ships with the radio is fine, and a headset is a better upgrade than a desk mic if you operate for hours. See the headset roundup.
• Ladder line and an open-wire feed system. Genuinely lower loss, and it brings routing constraints that make it a poor first feedline. Coax first.

What to upgrade first, in order

1. Height on the existing antenna, roughly free. Getting the high end of the end fed from 25 feet to 40 feet does more for DX than anything you can buy. Use the antenna height calculator to see the takeoff angle change.
2. A digital modes interface, $65. The Digirig Mobile digital modes interface$64.95 opens FT8, which makes contacts when the band sounds dead on SSB. Cheapest large increase in what the station can do.
3. A second, resonant antenna for your favourite band, $30 to $80 in wire. A monoband dipole beats a multiband compromise on the band it is cut for, every time. Use the dipole length calculator.
4. The Extra class license, one session fee. Opens the exclusive segments at the bottom of 80, 40, 20 and 15 m where the rare stations listen. See Amateur Extra.
5. Then, and only then, an amplifier. By this point you will know whether the limitation is power or antenna, and it is usually antenna.

Buying this build in stages

Stage 4 contains the grounding, and that ordering is a compromise with reality rather than a recommendation. If the antenna in stage 3 is a permanent outdoor installation, the arrester and the bonded entry point belong in stage 3 with it. The version of stage 3 that is genuinely safe to run without them is a temporary wire that comes down after each session.

How we chose these items

Selection is against three questions: does the station stop working without it, does a cheaper option create a problem you will pay for twice, and is it still the right item after the next upgrade. The RG-213 decision is the clearest case of the third, and the 30 amp supply is the clearest case of the second.

We research equipment from published manufacturer specifications, from Part 97 and the National Electrical Code where rules are involved, and from verified owner reviews at volume. We do not claim hands-on testing of equipment we have not used. Coax attenuation figures come from manufacturer datasheets and are matched-line values, so a real installation with connectors and a mismatch will be slightly worse.
