You will also incur this same 3-dB signal loss to your receiver. Perhaps the most talked about subject between Ham Radio operators is that of antennas. This is nothing new to our hobby. As a positive note, there are antennas that can be constructed in the VHF-UHF frequency range that are impractical to build at HF due to their large physical size alone. For our work throughout this article we will be referring to Vertical Polarization.
Horizontal mode antennas for mobile units are cumbersome.
The commercial communications industry was also firmly fixed on a vertical format as well. There are two major categories of vertical antennas we will discuss at this juncture. Antennas of this type come in many shapes and forms. Gain antennas are more costly and are in general much taller as the gain increases. As shown, this Yagi, or Beam antenna, may be mounted in the horizontal or vertical position as desired for your use.
