After running a big heliax line from the antenna to the house service entrance and properly bonding it (of course) what sort of run strategies do folks take from there to where the rig sits in the ho
Wow! I spent a couple of hours today trying to figure out what 7-16 DIN connectors to use for Andrew 7/8" heliax and I'm still confused. I suspec this is due to Commscope taking over the Andrew line
I'm just in the planning stages and not ready to buy yet. Perhaps I should just let the Commscope/Andrew dust settle. Their website is a bit of a mess. Anyone know if the AVAS line is replacing the h
I've decided I should get a better rotor and am considering the G800DXA. My mounting situation requires the bottom of the G800 be adapted for mounting atop a short mast. Does the GC-038 serve this pu
I've currently got a successful installation of a hexbeam almost directly mounted atop a Alphaspid which is in turn mounted on a 2ft aluminum mast. This whole thing is solidly held on a AB1342 cranku
Steve I helped PVRC install some of their dozen or so AB577 towers for FD2012. First time I've done it and they worked very well. Easy to put up and solid. Of course they're now rare as hens teeth. G
Check with users of HSMM. They repurpose 2.4G routers to do mesh stuff with ham radio. Colocation there for sure and they'd easily see any interference. 73 jim ab3cv _________________________________
My Alfaspid works fine but does make quite a grinding racket. Mine is only up about 35ft as I have a rather short crankup. If it was at 100ft no one would notice of course. whirring away but it does
I've been in touch with Alfaspid in Canada and MFJ where I bought it. It's coming off the tower tomorrow and headed back for warranty service as the noise is well beyond expectations. Thanks all for
In my searches I've not seen any 7-16 DIN connectors for LDF5-50. Do they exist? Thanks Jim ab3cv _______________________________________________ _______________________________________________ Tower
I've never assembled one of these. Does the center conductor come out and get soldered before inserting the connector on the coax for crimping? Thanks Jim ab3cv ______________________________________
I have a copy of the Yardley article. I was trying the concept to work up a 80/30 trap dipole but found that being too close to the third harmonic it was impossible for me to get both the 80m and 30m
Is it possible to thread an Alfaspid RAK-1 though the zigzag weave of either a Rohn45G or 55G? Not obvious to me. 73 Jim ab3cv _______________________________________________ ________________________
As a followup: does anyone know if the zigzag bracing and leg spacing of a Rohn25G will permit the insertion of a Alfaspid RAK-1? This "tower" will be at most 15ft high but guyed to support an EME ar
I'm getting ready to mount my beam atop my AB621. My location is the highest for a couple of miles around the trees here are often hit by lightning. I'm planning to ground my coax at the top and bott
Thanks all. I now know what I need to do. jim ab3cv _______________________________________________ _______________________________________________ TowerTalk mailing list TowerTalk@contesting.com htt
Light scatters as a function of wavelength and particle size to interact with. You see the results of scattering when you look on the horizon and on one day see a white haze which is scattering off w
McMaster-Carr has garolite in rod form. Need to cut to length and drill. Tough stuff and very strong. 73 jim ab3cv _______________________________________________ ____________________________________
