How do antennas actually work? What makes an antenna resonant, how does it radiate RF energy, and why do factors like impedance, polarization, radiation patterns, and antenna height matter?
In this video, we break down the fundamentals of antenna theory and explain the principles that every amateur radio operator should understand.
We’ll explore:
– How antennas radiate: How alternating currents and electromagnetic fields produce radio waves.
– Resonance: What resonance really means and why it matters.
– Impedance and SWR: Understanding feedpoint impedance, impedance matching, and reflected power.
– Radiation patterns: How antennas distribute RF energy in different directions.
– Gain and directivity: What antenna gain actually represents and why it doesn’t create additional power.
-Polarization: Horizontal versus vertical polarization and why orientation matters.
-Antenna height and ground effects: How installation conditions influence antenna performance.
-Efficiency and losses: Where transmitted power goes and why a low SWR doesn’t necessarily mean an efficient antenna.
Whether you’re new to amateur radio or an experienced operator looking to strengthen your understanding of RF fundamentals, this discussion will help you make better decisions when selecting, building, installing, and evaluating antennas.
Understanding antenna theory is about more than getting a good SWR. It’s about understanding how effectively your antenna radiates energy and where that energy goes.

🎃 Get a Signature 9 with FREE WORLDWIDE SHIPPING this Halloween!
👉 Claim the deal here: https://dxcommander.com/product/free-shipping-signature-9/
You MUST use the special link above to get free shipping — the offer won’t apply through the normal Signature 9 listing.
Want a proper HF antenna without guy ropes taking over the garden? The DX Commander Signature 9 is a freestanding, multiband vertical covering 40–10 metres, with a tune available on 6 metres too.
Fancy working 80 metres? Replace the 30-metre element with a longer wire, run it up the pole and out towards a tree or suitable support. It doesn’t need to be a perfect inverted L — I’ve had great fun running 80-metre pile-ups with a similar arrangement in Cornwall.
✅ No guy ropes required
✅ Ground-post mounting
✅ Lift it off the post when you need to take it down
✅ Supplied with our latest grey spreader plates
✅ FREE shipping worldwide through the Halloween link
International orders may still attract import taxes, tariffs and courier handling fees. Free shipping covers delivery, not those charges.

Uh Oh! The FCC Just Voted To Ban Chinese Radio Certification Testing!
Today the FCC voted to require all radio certifications to come from countries with Mutual Recognition Agreements with the USA. For all intents and purposes, this means China’s radio certification industry would be impacted in two years when the vote goes into effect. This impacts more than just radio to include phones, computers and cars. I expect that this vote will be documented in greater detail in the future. Until then, you can read their statement here: https://x.com/FCC/status/2115831011636604970

Hobbyist vs. Manufacturer: Why This Device Has TOO MANY SCREWS! #shorts
Opening a device with a broken knob reveals excessive hidden screws. While tedious, at least the internal hardware remains consistent unlike some other brands. A glimpse into the reality of DIY hardware repair.
