It takes into account the ever so slight bending of VHF radio waves along the earth’s surface. A UHF Radio is one of the more common pieces of technology found in four wheel drives, and for good reason. The 12-position fine-tuning control gives you the ability to hone in for optimal reception. Though it may not travel as far, UHF radio waves will traverse around obstacles better than VHF. These VHF/UHF radios come in two varieties - one that look like toys, but are actually quite powerful. If you don't like the range you can add a better. The PR9560 is intended for land forces such as infantries, more AT AR20 Automatic Rebroadcast Station.

VHF, or “very high frequency” is a range of radio frequencies between 49 and 216MHz. It broadcast on 433Mhz at 500mW and has been proven to control your RC effectively up to 25KM +. Another point worthy of mention is that GME radios are the only UHF radio manufactured in Australia and, from my experience, are built tough to last. Both VHF and UHF are too high in the frequency range to bounce off the ionosphere like AM radio transmissions in the High Frequency range, which. I don't know how much it matters between brands but in the interest of keeping comparisons as apples-to-apples as they can be I'll give a few examples of GME radio range as I'm a bit familiar with them.

AM radio (550 kHz – 1650 kHz) and shorter wavelengths in the sub 2 MHz range follow the earth’s curvature due to reflection off of the atmosphere and thus travel pretty far. AN_9144 Range Calculation for 300 MHz to 1000 MHz Communication Systems This paper begins by introducing the Friis Transmission Equation and examining the terms comprising it. Differences in Spectrum Range. About UHF Crystal Radio The resource is currently listed in dxzone. Motorola GP339 VHF/UHF Radio.
