a lot of people rate the avanti sigma iv highly. could it be updated? improved upon(change tuning?) and made stronger, more bullet proof? i am sure it would be a big seller.
as far as the original post goes on this thread, in the days where many companies are winding down/ stopping production of radio antennas and equipment, if a guy can produce an antenna which is of such quality and performance that radio operators rate it better than many well known "greats" from over the past twenty years, then i take my hat off to this guy who is dedicated to our hobby,and look forward to trying one out in the uk one day.all the best ,you are taking the hobby in the right direction.cheers!!
