🔥 Frequently Asked Questions

📡 Getting Started

What antenna do I need for my radio?

It depends on your frequency, not the radio brand. VHF, UHF, and 900 MHz all require different antennas. If you're unsure, contact us and we’ll match you with the right one.

What frequency is my radio?

Most radios fall into:

• VHF (136–174 MHz)

• UHF (400–520 MHz)

• 900 MHz
  Check your radio specs or send us your model and we’ll identify it for you.

What connector do I need?

Connector type depends on your radio. Common options include SMA Male, SMA Female, BNC, and more. Send us your radio model and we’ll make sure you get the correct fit.

📶 Performance & Tuning

Does a longer antenna mean better range?

No. Antennas are based on tuning, not just size. A properly tuned antenna will outperform a longer antenna every time.

What does dB gain mean?

Gain changes the shape of the signal, not the power.

• 3 dB = wider coverage

• 6 dB = more range

• 9 dB = maximum distance in open areas

Will your antenna improve my range?

In most cases, yes. A properly tuned antenna with low SWR improves signal strength, clarity, and overall performance.

What is SWR and why does it matter?

SWR measures how efficiently your antenna is matched to your radio. Lower SWR means better performance and less signal loss.

Can I use one antenna for multiple frequencies?

Not effectively. Antennas perform best when tuned to a specific frequency range. Wideband antennas are always a compromise.
