I have a problem with my 70cm cir Pol yagi. A feed line got tangled in the antenna apparently when I moved the antennas from a high angle back to 0 degrees. A driver element was bent and nearly pulled completely out of the insulator and matching unit. I pushed it back in through the insulator but the analyzer shows no resonance at frequency. Is it possible to open up the small matching unit box and repair such a problem or am I destined to buy a new unit from M2?

Cracked it open and look. Nothing fancy inside. Just a relay and connecting wires. Sounds like one is broken.

Richard,
What is broken? The feed block or the splitter used to generate the CP wavefront?
Can you send me a picture of the broken item?
