An HF station is four things: a radio, an antenna, something to feed it power, and something to connect them. Everything else is optional, and a great deal of what gets recommended to newcomers is optional.
The single most common mistake is spending 80% of the budget on the radio and buying whatever antenna is left over. That is backwards, and the rest of this guide is mostly an argument for why.
Spend on the antenna first
A modest radio with a good antenna will outperform an expensive radio with a poor one, every time, in both directions. This is not folklore — it follows from how the system works.
Your transmitter’s power is fixed by regulation and by your wallet. The antenna’s job is to convert that power into radiation in a useful direction, and a bad antenna throws much of it away as heat and into the ground. Meanwhile, on receive, HF is externally noise-limited: the noise floor you hear is atmospheric and man-made noise arriving through the antenna, not noise generated inside the radio. A better receiver cannot help you hear a signal that your antenna is not capturing above that noise. A better antenna improves the signal-to-noise ratio on both sides of every contact.
A useful ratio for a first station: one third radio, one third antenna and feedline, one third everything else. If your antenna budget is under $150, you are building it yourself, and that is completely fine — a 40 m dipole is wire, insulators, and an afternoon.
Three working stations
~$600 — get on the air
| Item | Choice | Approx. |
|---|---|---|
| Transceiver | Used Yaesu FT-891 or Icom IC-718 | $450 |
| Antenna | Homebrew 40/20 m fan dipole or EFHW kit | $60 |
| Feedline | 50 ft RG-8X, pre-made with connectors | $35 |
| Power | 30 A switching supply | $60 |
Buying used is the right call at this level. HF radios are simple, durable, and hold value; a ten-year-old rig from a ham who took care of it is a far better purchase than a new radio at the same price. Club members will tell you who is selling.
~$1,500 — the sweet spot
| Item | Choice | Approx. |
|---|---|---|
| Transceiver | Icom IC-7300 | $900 |
| Antenna | Commercial EFHW or 40 m dipole, well installed | $150 |
| Feedline | 75 ft LMR-240 or RG-8X + common-mode choke | $90 |
| Power | Linear 25–30 A supply | $180 |
| Grounding, connectors, SWR meter, misc. | $180 |
The IC-7300 is the default recommendation for a reason: a direct-sampling SDR with a real-time spectrum scope, and a single USB cable that carries both audio and rig control, so digital modes work with no extra interface. The spectrum scope in particular changes how you operate — you see where the activity is instead of tuning blindly across a band.
~$3,000+ — no compromises
Add a better antenna before a better radio, always. In order of impact: a directional antenna (a hexbeam or a small triband yagi on a rotator) then a tower or mast to get it up, then a radio with better close-in dynamic range, then an amplifier.
For a horizontal wire antenna, height above ground dominates performance — it sets your take-off angle. A dipole at 20 ft is a fine regional antenna and a poor DX antenna; the same dipole at 45 ft is a genuinely good DX antenna. Before spending money on a fancier antenna, spend effort getting the one you have higher.
The parts people get wrong
Power supply
Get 30 amps at 13.8 V, not 20. A 100 W HF radio draws roughly 20–23 A on transmit peaks, and a supply running at its limit sags, which shows up as distorted audio your receiving station hears but you never do.
Linear versus switching matters more on HF than anywhere else. Cheap switching supplies generate broadband hash that lands right on top of the bands you are trying to listen to, and can raise your noise floor by several S-units. You can spend $400 on an antenna and give it all back to a $50 power supply. Good switching supplies exist — but a used Astron linear is heavy, boring, and quiet.
Coax
For HF at typical runs, RG-8X is fine and RG-58 is acceptable under about 50 ft. Loss on HF is low enough that exotic cable buys you very little.
That changes completely above 50 MHz. At 2 m and 70 cm, feedline loss is serious, and RG-58 on a 100 ft run can eat most of your power before it reaches the antenna. Use LMR-400 or better for VHF/UHF runs of any length.
Buy pre-made assemblies with factory connectors until you have learned to solder PL-259s properly. A bad connector is an intermittent fault that will cost you an entire weekend of confused debugging.
The thing nobody mentions: common-mode current
If RF comes back down the outside of your coax shield into the shack, you get the classic beginner symptoms: the SWR changes when you touch the radio, your computer’s USB drops out on transmit, the microphone bites you, or people report distorted audio.
The fix is a common-mode choke — a coiled section of coax or a ferrite-cored current balun at the feedpoint. An EFHW in particular almost always needs one, because it uses the feedline as part of its counterpoise unless you stop it. Budget $30 for this; it solves problems that otherwise look unsolvable.
What you do not need yet
- An amplifier. Going from 100 W to 1,000 W is one S-unit and change at the far end. It is the most expensive dB you will ever buy. Improve the antenna.
- An antenna tuner, if your antenna is resonant on the bands you use. A tuner does not improve a bad antenna — it makes the radio comfortable driving a mismatch, while the loss stays out in the feedline. It is genuinely useful for multi-band wire antennas, but it is not a substitute for an antenna that works.
- A fancy microphone. Stock hand mics are fine. Audio processing that sounds great in your headphones frequently sounds worse on the air.
- A second radio. Learn the first one.
Where to put it
A little planning here pays off for years.
- Get the feedline into the building sensibly. Through a window panel or a wall entry, with a grounded entry point outside. Do not run coax through a window you need to close.
- Ground the entry point. A ground rod at the entry, bonded to the house electrical ground. This is lightning safety, and bonding to a single ground system matters more than the number of rods.
- Disconnect when you are not operating. The best lightning protection anyone has ever devised is an unplugged coax sitting outside the building. Weather comes in, coax comes off.
- Sit comfortably. You will spend more hours here than you expect. Desk height, chair, and where the logging computer sits all matter more than they sound like they do.
A first-week checklist
- Put the antenna up and measure SWR across each band you plan to use. Write the numbers down — they are your baseline for diagnosing every future problem.
- Listen for a week before transmitting. Find the nets, hear how contacts actually flow, learn the rhythm of a pileup. This is free and it is the fastest way to stop sounding brand new.
- Make your first contact on a scheduled net rather than by calling CQ into the void. Net control will find you, hand you a turn, and be patient about it.
- Log everything from contact one, including the failures. You will want the history sooner than you think.
