- That could be the source of the higher than normal SWR on 12. The factory specs are for "~3.2" with 100 feet of RG-213, although I run 70' of RG-213, connected to 50' of 7/8" Heliax and get around 5:

- Dennis: I would be interested in a design like you suggested. Here's another though I had. Could a relay box be inserted at the main DE feed (like F-12 does with their 80 meter antennas) that re-tune

- I'll give that a try! I'm still thinking about some arrangement of using a relay to switch in an appropriate matching component. I wonder if anyone knows what the R/X values are at 12 meters? Ron N6A

- I measured 400 - 500 ohms on 12 meters at the main feed. The 40 meter section showed 10 ohms and the 75 meter F-12 rotatable dipole was 30 ohms. Measurements were made with an older MFJ 259, so I don

- Michael: Been there, done that! You have water in your traps, and running even a little bit of power has zapped one or more of the insulators inside the traps. The first time I did that on my A-4, I
