Can higher gain antennas be used?
As long as the signal strength does not exceed 4 Watts EIRP, the end user may use a high gain antenna. With the BreezeCom radios we use, we have thought to try, using an LNA on a directional 30 dbi gain antenna, on a dedicated receive antenna port. This would be used on a very long haul connection. We would then use a standard 24 dbi directional antenna as the send side. Repeat at the other end. Normally a 30dbi antenna would be dissallowed under the FCC guidelines, but by using the ability to turn the antenna port into a receive only we can access the better “ear”. Higher gain Omni directional antennas are also in use by many people.
