FYI - Force 12 went to six rivets per element joint, up from three, two
years ago at the advice of "Mr YagiStress" Kurt K7NV. Three are on each
side of the tubes providing a nice secure and stable grip. Larger tubes,
1.25" OD and up, get eight, four per side.
We can sell you rivets however you can just as easily go to McMaster-Carr
(who have insanely fast service) or a hardware store in your town. 1/8"
aluminum blind rivets will do the job on your Tennadyne LPDA. Get a pop
riveter with good leverage or better still a pneumatic rivet gun for your
shop air compressor, your forearm will thank you!
