I seem to recall that a fairly new subscriber a year or two ago came up with the notion that it would be good to start a housing development with the express purpose of selling to hams. I believe he
Ya know.... A funny thing happened when the Board of County Commissioners met to discuss the antenna tower question at our family QTH. They were very concerned that by allowing us to pursue our anten
A Amateur trading Post, that's what we need Bill. 0,33 $ cents... ,Affraid your tax administration or VAT will bring the price up to at least 0,7 $ cents. With two vendors following the cycle, they c
I've seen the transient suppressors that use a standard gas tube spark gap with a probe to the center conductor of the coax. I think they just make the dimensions such that the mismatch isn't all tha
I've gotten a ton of positive replys to my last message and am just sitting here thinking off all the other stuff that happened while I worked as a commerical tower installer and thought that perhaps
Typically you want 2 to 4 PSI of pressure in the transmission line. Andrews the company that sells Heliax and antennas sells a dehydrator that is used a lot at broadcast transmitters. I had to purcha
Several approaches spring to mind, and some analysis as well.. Look at your flow rate and the pressure you're using and see if you can bound the number of pinholes. Flow through a small orifice is so
Paul, It's been almost six years since I've used my GAP Titan. It's still erected in the woods as an emergency backup antenna, but now that I have at least two other superior antennas on each band fr
Well, It's is up in the air, on a 12 foot mast sunk 4 feet in concrete sticking above ground 8 feet On 20M....Testing it compared to a Hustler 6BTV and Cushcraft MA5V as a reference. Results vary as
Jim, I have not heard a lot about the Sigma 80 except what I've read on Eham and also from a ham friend of mine in Washington using a pair as a phased arrayHis antennas are sitting in a lake off a do
I'm not totally sure about this but there is a uhmw we use in our materials handling chutes that is supposed to be uv stabalized. Its called "TYVAR 88". There are several grades of TYVAR but the 88 i
The natural color (white) UHMW will last ~2years in the sun here in the southeast before the UV breaks it down into a crumbling mess. Nylatron, on the other hand, is a similar plastic but impregnated
Hello to all: Just a note about these cutting boards. Most restaurants use these and have to replace them from time to time for health department reasons. When they do, they just toss them. They are
boy this is tough - possible upside on the lower frequencies if you both put up decent sized towers they can be far enough apart you could share towers as antenna supports - a 160 meter dipole sudden
And to tailend on Bill's remarks.... ....having Towertalk keeps there from being more poor choices made when towers are installed... tnx K7LXC for probably avoiding some of those potentially life thr
Andy, It really depends on your fitness level. At age 58 (or so), and in the 135th percentile on a treadmill test, I took me about three days, but that included lots of rest stops, distracting phone
When I lived in the Los Angeles area, we had a club at work which put up a 40 ft tubular tower with a HAM-3(?) rotator and TH6DXX (also a ringo ranger 5 ft above the yagi). The tower was roof-mounted
I believe the windload rating is 10 sq ft at 50 MPH. What kind of antenna will you be putting on the tower and what's the windload? My experience with the 72' version (the MA-770) is that when the wi
