Replaced my a99 up about 38 feet in top a oak tree.with no radials on 5 foot of mast with no ground plane kit i did fairly well talked most of the world with 400 watts peak power in 2014 with great cycle 24 conditions.i recently put a aluminum ar 10 ringo in the same spot and my rx got much better and quiet and great dx results and local compared to a99 withhorrible 2017 zero. Sunspots.in my situation needing a no radial vertical the ar 10 beats the imax and a99 for local and dx up 30 feet...
