Yea, crazy is the correct word, especially the last 150 miles!! Look forward to comparing notes with you later this month.

I contacted the manufactures Tram and Practical Sailor published my complaint. Crickets from the manufacturer. I need to go to a different antenna. I will check out the Shakes unit. Having the antenna fall off is dangerous, esp. if you don't notice it's missing for awhile.

Mike, when you say that you lost the antenna, what do you mean? What fell off? I fail to see how the antenna can just fall off as it's attached with a large nut.

Geoff,

It is a very poorly designed antenna IMO. What happens, and I was able to simulate this in my garage, is the circular wipping of the antenn while underway actually walks the antenna asembly off the mount.

The antenna whip is seated and welded or crimpped into a bullet shaped base. This base has a female threaded socket which screws into the male thrreaded post on the mount which is attached to the mast cap.. There are no set screws in the bullet shaped base. Although this time I applied a lot of torque and locktite, the bullet shaped base seemed to have, once again, walked itself off the threaded male stud on the mount.

I know it soulds hard to believe but I was actually able to make this happen by simulating the ships motion with my hand and seeing if I could walk the whip off the mount. I could actually do this. I though a lot of torque and some locktite would solve the problem. Apparentle not.
