connection, it is the factory mad connection of the boom--boom connector of my Magnum 620. These rivets are 120 degrees in 3 sets, but they are all fall down, just 2 years after have the beam up on the tower. A simple bolt will help, but how to climb 30m and then go 4 m outside off the boom. I think, Force12 must look for a better technology to assemble this. (I had the D-Model, so for extrem winds) I dont see any words from the factory himselfe about this problem. I really disapointing about this on my antenne. Not a good construction for those money we had to pay for the antenna. M² monobanders looks much better in mechanical construction. I believe this would my first and only Force12 Antenna. 73 Wil DJ7AA K7LXC@aol.com schrieb: > > In a message dated 2/26/01 9:59:28 PM Pacific Standard Time, list@qth.com > writes: > > > Surprise surprise, yet another story of rivets failing on Force12 > > antennas.
