I am in no way trying to win any contests or anything, I was just passing something along that worked for me. It may not work for the next person, but did for me. I took into account the added weight and compensated by adding 5 5" magnets to the underside of the roof below where the 145 mag mount sits. I promise you that it isn't moving. Inhale been to highway speeds of 70 now and no issues. Like I said I bent the whip back until it was about parallel with the roof as well to test the magnets strength. It holds. It was never about increasing bandwidth, only to try and improve over the stock whip, which it seems to be doing this fine. Swr readings are actually a little better with the larger whip. 1.1-1.2 across the whole 11m band. I could probably tweak the whip a little and get the swr readings down but nobody on the other end is going to notice the difference. I have made and also inquired from the same people I talk with daily and have not had any reports of signal loss and I have been talking dx today as well. Like I said I was just simply trying to pass some info along that may or may not help some one else. God bless and happy holidays to all. 73's.

[QUOTE="222DBFL, post: 456080, member: 36544"] I am in no way trying to win any contests or anything, I was just passing something along that worked for me. It may not work for the next person, but did for me. I took into account the added weight and compensated by adding 5 5" magnets to the underside of the roof below where the 145 mag mount sits. I promise you that it isn't moving. Inhale been to highway speeds of 70 now and no issues. Like I said I bent the whip back until it was about parallel with the roof as well to test the magnets strength. It holds. It was never about increasing bandwidth, only to try and improve over the stock whip, which it seems to be doing this fine. Swr readings are actually a little better with the larger whip. 1.1-1.2 across the whole 11m band. I could probably tweak the whip a little and get the swr readings down but nobody on the other end is going to notice the difference. I have made and also inquired from the same people I talk with daily and have not had any reports of signal loss and I have been talking dx today as well. Like I said I was just simply trying to pass some info along that may or may not help some one else. God bless and happy holidays to all. 73's. [/QUOTE]
