Yagi on GMRS: Should I go vertical or horizontal?

[Josh380]

I've had my yagi setup on a non conductive push up mast, vertically polarized, for quite some time time now, and a friend mentioned my signal might be better if I changed it to a horizontal polarization. I've done some reading on this and it seems that in a line of sight situation, with a direct, unobstructed path to the repeater antenna, I might get the most amount of gain from my antenna.

Thoughts? Has anyone tried this on GMRS?

Gmrs is Vertically oriented so there ya go ! Horizontal is fine IF your other stations are also Horizontal.

Depends on if you are communicating with other vertical or horizontal stations.

You will get a lot of loss mix matching polarization's.

I'd stick with a vertically polarized set up. The repeater antenna is more than likely vertically polarized.

Since GMRS is a mobile/portable radio service, and most mobile and portable antennas are vertically polarized, the repeaters are too.
You will lose some signal trying to do a horizontally polarized antenna to talk to vertically polarized antennas on repeaters, mobiles and portables. Others said this above, just reinforcing it.

You can run horizontal polarization if -everything- you are talking to is the same way. It's find for fixed links. A good way to reduce some interference from co-channel users.
