Did you have to do any thing to your radials such as shorten them ?

No I didn't shorten them, I set them per the instructions and things worked out fine. Setting the height for 11 meter is the important thing and every bodies install can be a little different. But for starters I believe you could start at 22' 9.5" and adjust from there. I've been playing with mine for a year and mine is set at 22' 9" and I think I could shorten it by maybe a 1/4- 1/2" but the SWR is good so it probably won't get done.
