What is the effect of antenna cross-polarization over a line-of-sight VHF or UHF path?
Pick an answer to check it.
Answer: B. Received signal strength is reduced
When one station's antenna is vertical and the other's is horizontal, the received signal strength is reduced, often by a lot. On a line-of-sight path, matching polarization matters.
Tip: Match your polarization to the other station.
