Do you need antenna tuner for UHF VHF?

Do you need antenna tuner for UHF VHF?

On the VHF/UHF bands, antenna bandwidth is not as much of an issue. A 2 meter antenna with 7% SWR bandwidth (nominal bandwidth for a Yagi), will easily cover the whole 2 meter band with a reasonable SWR. So if the antenna is tuned properly, no tuner is needed.

Does antenna tuner reduce power?

Antenna tuners are used almost universally with solid-state transmitters. Without an ATU, in addition to reducing the power radiated by the antenna, the reflected current can overheat transformer cores and cause signal distortion. In high-power transmitters it may overheat the transmitter’s output amplifier.

Do UHF antennas need tuning?

All Mobile One UHF Antennas do not need to be tuned, they are very broad-band and will have a SWR below 1.5 to 1 as long as they are installed correctly.

Does VHF antenna need tuning?

If you buy a commercial marine VHF antenna you only have to connect them together. It’s already matched. And, there are no adjustments that you can make. By far the vast majority of Marine VHF antennas cannot be tuned.

Do antenna tuners reduce power?

Antenna tuners are used almost universally with solid-state transmitters. Without an ATU, in addition to reducing the power radiated by the antenna, the reflected (or “backlash”) current can overheat transformer cores and cause signal distortion.

Can you use a UHF VHF antenna for CB radio?

An antenna needs to be resonate at the frequency you are transmitting on. That means the antenna used with a CB needs to be designed to work on CB frequencies (26-27MHz). A VHF/UHF antenna isn’t going to be resonate on those frequencies and will perform extremely poorly.

Does a VHF antenna need to be vertical?

No matter how tempting it might be to angle your boat’s VHF antenna for aesthetic purposes (like matching the angle of fishing rods), don’t do it. Sure, it looks sleeker to have them angled, but they’re designed to be positioned upright for a reason.
