Al, I had exactly the same problem with my T2X. Replaced the cap just like you did with same results. I finally took the two halves apart and checked out the gear drive mechanism. With the brake rele
Allan, I presume you are missing the two rods as well as the shorting clamp for the beta match. The physical size of the beta match is determined by the amount of inductive reactance needed to transf
Howdy, When I put together the article in volume 2 of the compendium I used two Butternut HF2V antennas with great success. Since then Ive used full size monoband 40s, monoband 20s and mix and match
Howdy, I find myself in the embarrassing position of having to correct a stupid mistake that was made when my TH7 was reassembled after repairs from storm damage. As we were bolting the TH7 to the ma
The TH7 boom is pinned in the clamp with two bolts and cannot be rotated. Bob _______________________________________________ _______________________________________________ TowerTalk mailing list To
There is a good article on stacking dissimilar antennas on the array solutions website. w5ah _______________________________________________ _______________________________________________ TowerTalk
My solution has always been to crimp AND solder. never had a broken antenna connection Bob, W5AH _______________________________________________ _______________________________________________ TowerT
Gentlemen, Sounds to me like something has been changed in the manufacturing process for the T2x. I bought one about 6 years ago and have had the exact opposite problem... the bolts will not stay tig
Howdy, The U- shaped aluminum wire that forms the end of the beta "coil" does not have to be grounded to the boom. The end is an electrically neutral point and the ground serves only as a mechanical
I have a couple of homebrew 4 el on 3/4 wavelength boom yagis with gamma matches. The antennas were designed to have a -j component at the feedpoint. Using a gamma match without a capacitor resulted
The gamma match inductance has the same effect as adding a loading coil to the element thus making it electrically longer. Reducing the physical length of the element moves the electrical length bac
Norm, A 75 ohm coaxial 2:1 impedance transformer does perform a BALUN function when wound into a coil or when several turns are wound on a suitable toroid. 73, Bob, W5AH _____________________________
Norm, Correct, it is an RF choke. A BALUN works as an RF choke in series with the outside of the coax shield Bob _______________________________________________ ______________________________________
