I'll mention this just because it's a concept unique to the SteppIR design. I don't know how you might implement it in your situation. When I installed my SteppIR initially, I mounted it in the tower
Several years ago I bought an 8' fiberglass mast. I could have sworn it was from AES or HRO but now I don't see it. I'd like to find another 8' mast and a 12' to use as a boom. Shipping will obviousl
I recently acquired a Hygain 6m yagi. It uses an open-wire coax feed (coax connected to two screw terminals). I'm concerned about corrosion and water ingress in the coax. What is the best technique t
Electrically the thing is just a big whip. Physically it's a massive machined stainless steel base with an insulator. I haven't measured it but the whip is also very thick (3/16", maybe 1/4" stainles
I have no idea what the design criteria were. Looking at the thing, I have to assume it was made for the land mobile market, not amateur. It is a massive machined stainless part. It is clearly built
CenterPin makes a nice model for RG-8X and RG-58 that's sold through Shakespeare http://www.shakespeare-marine.com/electronics/accessories/centerpin.htm. I don't see a version for RG-8U. CenterPin al
For me the visual impact of the SteppIR is a clear advantage. I'm looking forward to upgrading my 3 element with the new 30/40m driven. This small antenna size lets me add additional antennas for VHF
How true. It took a bit of selling to get a decent tower, however. The best pitch was an aerial photograph of the house from the county and a handmade overlay showing the guy footprint of a 140' towe
I looked up this docket number and the coment period I see was over by January 28, 2005 http://hraunfoss.fcc.gov/edocs_public/attachmatch/DA-04-3891A1.pdf. It references a study in 2003 and I found i
Many years ago I found a lonely-looking rotor at a hamfest. It was just the rotor itself - no controller, manual, mast clamps, etc. It was brand new, no scratches or dirt and looked EXACTLY like one
The current (some say "dumbed down") Technician class question pool has a question on tower grounding. There's no reference given (I would like to find it). T0B11 (C) What is considered to be an adeq
I'm getting ready to order a new mast clamp for my Orion 2800. Is there another version I should look for? Scott N7SS that the mast clamp slips, or the rotor breaks? I purchased a heavy duty Slipp-No
I actually had my Rohn 45 fold-over done for real. It was only $.50 a pound and they prep it to remove rust (removing paint is more). I was concerned about holes filling with zinc - especially the hi
I always felt the element spacing was ideal for most applications. It provides high front to back ratio on 20m where noise is often an issue and high gain on 10m where gain is generally more helpful
Our Emergency Operations Center received a "standard Winlink package" that consisted of an Icom IC-M802, AT-140, wire and an SCS TNC. We mounted the tuner at high on our 40' tower as the tuner contro
I plan to do exactly this on my new tower. I shopped for cameras for quite a while and ended up buying the Toshiba IK-WB15A (and older IK-WB11A - no optical zoom or PoE) for another installation I ha
The NCVEC at http://www.ncvec.org/ controls the content of the question pools. They also accept question suggestions on that page. With all the "dumbing down" of ham radio comments, it's easy to beli
Has anyone tried that CLR (Calcium, Lime, Rust Remover) stuff on towers? I'm sure it would work on the rust but I'm not familiar with the chemical process so I don't know what effect it might have on
Most hardware store pulleys are crap. They're heavy, made of cheap metal with poor load ratings. They're just a metal wheel in a housing with lots of slop and a bad axle. The slop allows the line to
