    Well, I don't think you'd be making any kind of mistake by installing 
either one of those antennas. 

    Does the linear loaded 40M work as well as a full-sized version? No - the 
LL design is a compromise. 

    As far as the potential mechanical problems, double or triple-row the 
rivets per joint and they won't come apart. Make sure the element 
boom-to-element brackets are backed up with thru-bolts. And pay the extra 10% 
for the upgraded 100 MPH version.
