Hi All, I am not going to buy into your debate about which is the best aerial. The one in the first post is a Dipole aerial, and in the photo it is mounted up side down. I have used that aerial for over 20 years on trikes. I also have one of the best radio responces from airservices and other aircraft. You need to have a full system, that means radio, aerial, and comms. get it right it works, get it wrong it give you a problem. If you don't believe me as David, or, Glen or anyone that has been on a Megafauna Flyaway, and they will let you know about my radio system.
All the best
Peter.
