Mouting of amateur wire antennas

Losses in an antenna due to the ground, without speaking of the feeder and coaxial, are of three kinds.. The main problem is the antenna ability to pick up passing waves near conductors. And of course for licensed hams these effects will affect your "angle of fire". The equivalent long wire is twice as long. Now compare these properties to the ones of a small VHF Yagi. A G5RV multi-band dipole of 31m long ft coupled to an open-wire feed line of about 10m long.

Hf Antenna Installation Hints
The questions to which we are going to answer are what aerial to choose to get a good signal, where and how to install it. Indeed as we introduced in discussing about Basics of antennas , an antenna dedicated to only receive ham emissions does not have to be as "perfect" as a transmitting antenna, and still more, it "works" not at all in the same way as in emission. However, and this is a good news, the gain of both antennas is not affected by the frequency and both systems are able to capture the same amount of energy in respect with their specifications. On the contrary, in receiving the pickup efficiency put at the disadvantage of listeners because the physical length of the antenna directly influence the amount of energy that it is able to pick up. These few problems are of importance in HF bands as their wavelengths measure between and 10 m long And of course for licensed hams these effects will affect your "angle of fire".

How do i mount an end
So, even if that sound like a contradiction, a receiving antenna is not as critical in some respects as a transmitting antenna. A very small VHF Yagi for example should be thus as efficient as a HF beam 10 times larger if we can ensure it a high gain at high frequency the pickup efficiency decreasing indeed as the frequency increases, what can be improved in using Yagi's with still more directors. The most important is the physical size of the antenna used, then its radiation pattern. For active hams theses questions may extend to the effects of some materials and soils on waves propagation.
