I have made the purchase of an AB-621/G mast from a surplus supplier. The unit should arrive next week. I haven't seen it up close yet, so I'm wondering how much I'll need to disassemble it in order

Thanks, I should have mentioned, I do have a small tractor and welded up a fork lift for it this summer. I suppose I could put straps around the base section and pull if off the ground with the fork

Hi All, Does anyone have any experience with the spiderbeams? I would really like to put up something light-weight for 40 meters. I believe the spiderbeam 40m unit is only 17 pounds. Not sure if anyo

Yes, the Hex appears to perhaps be the easiest due to the shorter lengths needed. I would guess that for 40m the spreaders would each be no more than 29 feet long. I believe Max-Gain sells their "typ

I'm pretty sure RG142 or RG303 are both used for toroid baluns. If I remember they are spec'd out by the W2DU choke balun. 12 turns wrapped pretty tight around an FT-240-61. -- Bw_dw@fastmail.net ___
