OK, there are many factors that will affect your radio reception in YOUR location. Most importantly is the topography around you. If you live in and area where you are high in elevation, you should get some good reception. VHF electromagnetic propagation is known as Line-of-Sight (LOS). Like a flashlight, it can only transmit in straight lines. This differs from lower-frequency radios in the HF range, such as HF-SSB or Citizen?s Band (CB) radio that can rely on "skip" to transmit long distances. For this reason, the transmission/reception range for VHF marine radios is effectively limited by the curvature of the earth and antenna height. In this regard, the higher you can mount your antenna, the further you will be able to communicate. Of course, this is simply because the line-of-sight for the higher antenna is greater.doubledip said:Is there any way I can listen to vhf in the san fernando valley?
It highly unlikey you'll receive any transmissions, due to your onshore distance and surrounding elevations.doubledip said:Is there any way I can listen to vhf in the san fernando valley?
