2 s units loss compared to an Imax and even more compared to a metal 5/8 has always been my experience with the a99, so maybe this isolation and radial thing is what it needs, but being an end fed 1/2 wave the entire cycle is completed from the base to the tip and back to the base so it doesn't really need the complimentary 1/4 wave radial system a 5/8 requires to complete the 2nd cycle after it goes up and back down through the effectively 1/8 wave matching network & 5/8 radiator.
