WebA UHF repeater operating at around 25W and an antenna 25m high would only achieve around 10 miles. VHF is ideal for vehicles that need a relatively wide range. Because the antennas are on top of the vehicles. Inversely, UHF having a shorter wavelength, can penetrate solid objects and make it's way through small gaps. Web6 Oct 2024 · 1. It is possible to design a dual band antenna using a single driven element in order to avoid the use of a diplexer (note the correct term for this device). On 2 meters, the driven element is ~1/2 λ long and on 70 cm it is ~3/2 λ long. Each band has its own reflector and director elements.
