Antenna Dbi

What gain antenna should I use for a distance of 110km over water using?Trying to use the back hauls to connect 2 islands.

What radios are you using?

Over water? :shock:

OS Spectra

I have several links using the same dish the furthest being 127.1km or 79.5 miles should work for you.

Gabriel QFD4-52 4ft Dual polarized Quickfire Parabolic dish 34.7dBi gain.
