A height of 120 feet or even higher will provide even more advantages for long-distance communications. To a distant receiving station, a transmitting antenna at 120 feet will provide the effect of approximately 8 to 10 times more transmitting power than the same antenna at 35 feet.
Consider line-of-sight vs/ height above average terrain (HAAT) for the frequencies used. Vertical antenna patterns less affected by the ground than horizontal. 40’ seems to be the optimum height for horizontal 6m beams. Microwave. Line-of-sight, Fresnel-zone clearance are both critical.
Essentially, the antenna tower must rise no more than 1/100 the distance from the tower to the nearest edge of the runway if the runway is greater than 3200 feet long. If the runway is 3200 feet or less, the tower height may extend up to 1/50 the distance to the nearest edge of the runway.
In terms of "cost per foot", the guyed tower is the most economical. However, you must have enough space for the guy wires!Guy anchors should be installed away from the base of the tower at a distance of between 60% to 80% of the tower height. (Follow the manufacturer's instructions).
The height of your Antenna is important for ham radio contact, so if your ham radio antenna is low to the ground then it will have less ham radio signal. The best height for a ham radio antenna is between 10ft – 15ft off the ground.
27 Ιουν 2022 · Looking at the federal government on the use of a tower for a license amateur radio operator, I read that it is fine and a city can not limit the height of the tower. The amateur radio frequencies can be impaired if the proper heights are not met.
Radio masts and towers are typically tall structures designed to support antennas for telecommunications and broadcasting, including television. There are two main types: guyed and self-supporting structures.
