The short answer: Use Buryflex. It's the most flexible of the low-loss cables. My experience with coax on a crankup is both similar and different from Barry's. In 1997, I installed a 72' US Tower mot
Fortunately, my tower is located such that tree limbs aren't likely to fall on it. However, a friend of mine has a tower located on about 1/2 acre of cleared land bordered by woods. A number of years
The Master Appliance looks almost identical to the Solder-It. I've had none of the problems with my Solder-It that Rick describes. Been using it for many years, but almost exclusively with a solderin
I thought the iPhone 4 and 4s have special hardware for the compass function and the 3G does not. Is that true? 73, Dick WC1M I don't know about that owl, but *I'm* going to. I have a freebie compass
When IOS 4 first came out, I made the mistake of updating my old iPhone 3G. I soon discovered how to go back to older versions of the OS. There are lots of websites with instructions on how to do tha
I went with an extra 10-foot section. There are lots of advantages to that, including not needing a heavy-duty mast if you set the top antenna just above the top plate. In fact, since you don't have
I forgot to mention one of the more obvious advantage to using a 10' tower section instead of a mast: you can climb it with far less "pucker factor"! Seriously, it's not a lot of fun to climb a mast
Holy Cow, that is one massive antenna! Doug, since you have no prior experience erecting towers, I urge you to hire an experienced professional tower rigger to help you with this project. If you can'
This sounds terrific, Jim, and will be a huge boon to the amateur radio community. One question: are you proposing to generate .pro files with data out to the full 50-60 miles, or just what HFTA can
FWIW, I have a WB0W gin pole for Rohn 55G and wouldn't think of using anything smaller. What are the availability problems? If you can get the head and clamp, you may be able to find a 12-foot .25" w
You probably don't want to hear this, but you're really pushing it with a Ham IV turning 12.1 sq ft of antenna. I agree with Roger that the ratings on these rotors are generous, and they really need
It depends on the mast clamp. The M2 Orion is a big rotator, but the mast clamp design is seriously flawed, guaranteed to slip with a big load. The G-2800 is pretty good as clamps go, but regular ins
The creatures at my house *love* eating LMR400 (actually, LMR400UF). Eventually, I replaced it with BuryFlex and they don't eat that. YMMV, depending on your creatures. 73, Dick WC1M ________________

I've always thought that restrictive covenants were protected by the "inviolability of contracts" principle established by the Supreme Court, but my brief research on the matter confirms what Joe say
Beautiful! I'm sure you're really loud on 40 now! Let us know how the 40M2L compares with the 40m dipole on the SteppIR. Speaking of that, has the tuning on the dipole changed since you put up the 2-
Paul, Try Googling "RF Power Monitor Ethernet". These two commercial offerings look good (they appear to be the same), but also look expensive (no prices shown): http://www.aksolutions.com/Pages/AK88
I've used Top Ten A/B and 6x1 switches since 1997 for an SO2R switching array near a group of six antennas on my property (one of two such arrays.) I also use Top Ten 6x1 switches in the shack for sw
There's another reason to run cables inside the tower: protection. Maintenance often requires that you haul tools, parts, buckets, antennas, etc., up the tower with a rope. The stuff at the end of th
Not a stupid question at all. The answer isn't obvious. You can buy grounding kits for all sorts of coax cable. Grounding kits for heliax are usually for sale on ebay. They're relatively easy to ins
