- There are few products available to HAM community and all of them are very sophisticated tools. Some of them are able to switch up to four antennas in phase (stacks) and even out of phase to produce high elevation angle of radiation.
All of the available products are remote controlled, meaning that switching box is somewhere on the tower in order to phase two or more antennas for additional gain and lower take off angle (TOA).
