[TowerTalk] Hy-gain Hy-tower tuning on 15 Meters

[Gregg E. Salomone]

Hello:
I purchased a new hy-tower six months ago and am having difficulty with the 15 meter portion tuning the swr. I have followed the instructions to the letter and cannot get the swr down below 2.5:1 at best. I have 35 six gauge stranded radials buried in a 270 degree pattern.
The remaining bands are ok.
Is there a correlation to the radials or does anyone have similar commented about this same problem. I know that there could be many factors but I consider myself pretty knowledgeable about antenna construction and am puzzled with this one.
Any help would be greatly appreciated!
73 & thanks
