Xiegu G90 Review (2026): Specs, Tuner and Price
The short answer · Updated 2026
The Xiegu G90 is a 20 W HF transceiver covering 160 to 10 metres, with a wide range automatic antenna tuner, a 48 kHz waterfall and a detachable head. Buy it if you want the cheapest genuinely useful HF radio that will load almost any wire. Skip it for a high noise urban location or if you need Japanese-brand manufacturer support.

What it does well
- The wide range internal tuner is the headline. Very few radios anywhere near this price will load a random wire, and this one will.
- Twenty watts is a meaningful step above five, roughly 6 dB, and it costs almost nothing in size or current.
- The detachable head makes a tidy mobile or go box install possible.
- The 48 kHz waterfall is small but genuinely useful for spotting activity.
- A large owner community with a long history of firmware updates and documented modifications.
Where it falls short
- Receiver performance is the compromise. It is serviceable and it is beaten clearly by radios costing three times as much, especially near strong signals.
- There is no internal battery and no built-in speaker of any quality, so a field kit needs both.
- Menus and documentation are noticeably less polished than the Japanese brands, and support is through dealers rather than a manufacturer network.
- Twenty watts is still low power. On a poor antenna or a closed band it will not rescue you.
Why the tuner changes the maths
Most low power radios force you to bring a resonant antenna. That is fine on a planned activation and awkward when you arrive at a site and the only support is a tree in the wrong place. A wide range tuner turns that from a failed outing into a compromise that still works, and for field operating that flexibility is worth more than a few decibels of receiver performance.
What it does not do is make a short or badly sited antenna efficient. If you want the most out of 20 watts, put up as much wire as high as you can and use the tuner to clean up what is left. Size a starting point on the dipole length calculator or the end fed half wave calculator, and check what the feedline is costing you with the coax loss calculator. Your permitted bands and power come from your licence class and your national regulator, the FCC in the United States.
The G90 is on the Xiegu GPA100 compatibility list, so a 100 W station later does not mean replacing the radio. Read what the extra 7 dB buys before deciding it is the fix.
What owners report
Published owner reviews are dominated by one theme: the tuner. Operators describe throwing up whatever wire the site allows, letting the G90 match it, and making contacts, and they treat that as the radio's defining feature rather than a convenience. The 20 watt output is the second most praised item, because it is enough for SSB in a way that 5 watts often is not.
Criticism concentrates on the receiver and on polish. Owners in urban locations report more trouble with strong adjacent signals than owners in quiet ones, which is what you would expect at the price. The manual and the menu system are widely described as adequate rather than good, and support is a dealer matter rather than a manufacturer one.
A useful point that comes up often: the internal tuner will match a poor antenna, and matching is not the same as radiating. If the tuner is working hard, the loss is happening somewhere. Tuner versus resonant antenna explains where it goes, and the SWR calculator shows what the reflected power figure actually means.
Who it suits
- Field and portable operators who cannot control what antenna support will be available.
- New HF operators on a budget who want to make contacts rather than study specifications.
- Anyone who wants a second radio for the car or a go box without spending base station money.
- Operators in quiet locations, where the receiver's limits matter least.
Who should skip it
- Urban operators fighting a high noise floor and strong local signals.
- Anyone who wants a self contained portable with a battery inside. Look at the X6100.
- Operators who need a manufacturer support network and polished documentation.
- Anyone who needs more than 20 watts.
Alternatives worth considering
Xiegu X6100 HF and 50 MHz SDR Transceiver
Under $1,000
The same manufacturer's all-in-one, with a built-in battery, a nicer screen and 6 metre coverage, at 10 watts rather than 20. Better if you want one object to carry.
Check price on AmazonIcom IC-705 HF, VHF and UHF All Mode Portable Transceiver
Under $2,500
A far better receiver, a far better display and VHF and UHF all mode, for over three times the price and with no internal tuner at all.
Check price on AmazonYaesu FT-891 HF and 6 m All Mode Transceiver
Under $1,000
One hundred watts and a much better receiver for a few hundred more, at the cost of the internal tuner and the waterfall. The right call if you always have a vehicle battery.

Common questions
Questions people ask about this
How much does the Xiegu G90 weigh?
Xiegu lists the G90 at about 1.5 kg (3.3 lb) for the body with the head attached, which is heavier than the X6100 but light enough for a backpack when paired with a small LiFePO4 battery. Check the current listing for the exact figure, because the bundled bracket, microphone and cables add to the shipped weight.
Is the Xiegu G90 made by Yaesu?
No. The G90 is made by Xiegu, a Chinese manufacturer, and is not related to Yaesu or its FT series. Searches for a Yaesu G90 usually mean this radio; the closest Yaesu alternatives are the FT-891 at 100 W and the FT-710 for a desk.
What is the Xiegu G90 frequency range?
The G90 receives continuously from 0.5 to 30 MHz and transmits on the amateur HF bands from 160 through 10 metres, at up to 20 W on SSB and CW. It has no 6 metre, VHF or UHF coverage, which is the main thing the X6100 (adds 6 m) and the IC-705 (adds 6 m, 2 m and 70 cm) give you for the extra money.
What is the best antenna for the Xiegu G90?
A resonant wire is still best, because the tuner can match a poor antenna but cannot make it efficient. An end fed half wave or a dipole cut for your main band is the simplest high performer, and a 40 m doublet or a random wire lets the wide range tuner cover several bands. Cut lengths on the end fed half wave or dipole calculators on this site.
Is the Xiegu G90 good for a beginner?
It is one of the easier ways into HF, mostly because the wide range internal tuner removes the most common beginner failure: an antenna that will not match. Twenty watts is enough for SSB contacts on an open band. The trade is a receiver that will not keep up with an Icom or Yaesu, and support that comes from dealers and the owner community rather than from a manufacturer network.
Will the G90 tuner match a random wire?
In most cases yes, which is unusual at this price and is the main reason people buy it. It has a genuinely wide matching range rather than the narrow correction range built into most base radios. Remember that a match is not efficiency: if the tuner is working hard to load a short wire, power is being lost in the antenna system rather than radiated, and more wire higher up is still the real fix.
Xiegu G90 vs Icom IC-705: which is better?
They are different purchases. The IC-705 costs over three times as much and gives you a much better receiver, a large touchscreen, VHF and UHF all mode and an internal battery, but no antenna tuner. The G90 gives you 20 watts and a tuner that will load nearly anything. For contacts per dollar in the field the G90 wins; for the nicer instrument the IC-705 does.
Is 20 watts enough for HF?
For SSB on an open band with a reasonable antenna, yes, and it is roughly 6 dB better than 5 watts, which is about one S unit. For digital modes such as FT8 it is more than enough. What it will not do is punch through a pileup or rescue a poor antenna. Antenna height and length matter more than the difference between 20 and 100 watts in almost every real situation.
Does the G90 work for digital modes?
Yes, with a suitable interface for audio and CAT control, and it is widely used for FT8. Reduce power for continuous duty modes since the radio has limited heat sinking, and watch the internal tuner: retuning under a digital transmission is not something to do casually. Check the manual for duty cycle guidance before running long sessions at full output.
