on a 5/8 wave antenna , how much does the angle of the ground elements affect its performance ? if i understand correctly , a 1/4 wgp needs the sloped radials to be able to achieve 50ohms , but larger 1/2 wgp and 5/8wgp antennas dont . also , if i understand correctly the 5/8 wgp dont need full 1/4 wavelength ground radials to be able to perform at their best . but i see jay and maco and most of the older discontiued but still very respected 5/8wgp antennas use four 9 feet or just a little short of 9 feet horizontal ground elements .
is there a perfect ground radial length and angle for a 5/8wgp ?
also , ive read on ham forums about how only 2 ground radial elements are necessary and going to 3 or 4 gives very little increase . but they didnt say what frequency/band they were discussing and i know different frequencys react differently with their antennas . on the cb band would there be any advantage using eight 4 1/2 or 5 foot horozontal ground elements over four 9 foot H radials ? i know bob85 is a big fan of the sirio 827 (except for going open circuit) and it uses six 55 inch ground radials . sirios 2000 series seems to have a few fans in the mild weather areas and they use either sixteen 27 inch ground radials (2016) or eight to twelve 52 inch ground radials (2008 and 1012) . and of course theres the imax 2000 with no ground radials , but they will use the mast or coax as a ground radial if a elevated ground radial system isnt added it to it . i dont want my coax or mast to do that .
is all this just nit-picking and really doesnt ammount to a hill of beans as far as what will be herd when transmitting and recieving in the real world ? just do what ever is easiest ?
or is it something worth taking into consideration ?
