C3I ! http://www.c3iusa.com/ I had their C6 for a while (worked WAS and VUCC 300+ grids with 100W with it) which uses a 2" OD x .062 wall 19' boom and the elements are .5" and .625" x .058. These sec
Looking to do some comparison of antennas that I am interested in upgrading to. I've made up most I need, but have no spec's to make up one for a 50' boom 6M antenna like the C3I C13-50 or M2 6M9KHW.

OK, I must of missed this in the ARRL Ant book, what is the formula for simulating the effects of the mounting plate in YW? The YW.pdf tells you what the equivalent is but does not tell you how it go
Just took delivery of a 60' Heights folder over (non crank-up) a couple of weeks ago, actually it was personally delivered by Drake himself from Heights. I looked at this vs. a Tash (had a Tri-ex 37'
Anyone out there using a Force12 6M antenna, especially the EF-906? It's a classic OWA design and I modeled it using YW and it does compare to F12's published spec's. 50.000MHz | 12.71dBi | F/B 24.46
I had my new Heights Tower 61' tower inspected today for it's "Final Inspection" (which states that it must be done before "occupancy"), and found a note today that the inspector failed it! He said i
This time it passed. The inspector said he did not see the antenna mast as was shown on the drawings. Although it could be argued I just simply put the mast up there and he passed it. Gary Mitchelson
