This begs the question ..
I am getting ready to stack out and install my first "real" tower and
antenna system in next several weeks and would like to know what is the
correct way to properly install the feedline on a rotating yagi (Force12)? I
see mention of rotor loops and 2 turns around the mast, or single run direct
to balun. I had planned on using a pig-tail of LMR-400 ULTRA-FLEX between
feed (balun) and splice point on vertical run (LMR-400), below rotator. What
is the best way to minimize fatigue on the cable during rotation and
strain-relief the in-line joint? All suggestions appreciated!

Hello Mike,
If you dont want your $ to escape from your purse...... just close it, need
no pliers.
Same thing for RF .........hi .
But I learned over the years ( Mobile Radio install and after sales
service ) to use good connectors in critical applications such as Navy-type,
not the GP PL259's.
