The 100' roll of 3/16" EHS I ordered last week arrived on my doorstep Friday (UPS doesn't even knock anymore). Since I had never really cut EHS before (the tower came with the house), I checked the T
If you've got an antenna analyzer like the MFJ-359, you can see where the SWR is minimum. Cut off a few inches of antenna. See where the new minimum SWR point is. Then you can figure how many kHz per

Just get back from a round-the-world cruise, Steve? I posted my query a week ago. :-) Desperation overtook me and I bought a bolt cutter at Lowe's. I misstated it as an HK Porter bolt cutter because
What do you mean, Pete? Oh....ah...my expert typing and nimble fingers at work again... LOL....That's what I get for not proofing my work before clicking SEND. I wonder how many others will now respo
Some years back, the Texas DX Society 2m repeater started getting severe interference from a commercial repeater in town (Houston). We found out who it was by the CW ID and our repeater guy talked wi
Doug, Go to yahoo.com, do a search on '10m wonder bar antenna' and see what you get. Maybe between the number of the 17m and the 10m wonder bars, you can extrapolate numbers for other bands. 73, Dale
I don't know if I am in OT violation here or not...it's RFI, but in my Rotator/controller. Anyone having rfi problems in their AlfaSpid's on 40m? Other bands have no effect; only 40m...and at 20w, no

Last night, the local PBS station, KUHT/Houston, carried a program featuring the construction of the Gateway Arch at St. Louis. The arch was constructed in the 60's and, being pre-OSHA, the construct
That must be something new... I ordered my alfaspid back in December of 2005 ($1069.93) on my Visa card. There were no other charges related to the AlfaSpid to my Visa card. No one ever contacted me
Okay. Forgive my ignorance here. I'm not trying to be a wiseacre, but.... If vandalism access is such concern that you terminate the phillystran run out of reach, what do you do to secure your guy g
Roger, How important is 75m in your mobile operations? If you can live without it, the Yaesu ATAS-120 antenna system works with the FT-897. If you haven't considered it, there are a few plusses asso

I was worried about that when I installed it and thought about a fishing line guy, but it seemed stable when I moved the antenna by hand. I've kept a close eye on it and check it at least once a wee
I'll bet Phillystran, Inc., would know (know for sure) which dealers carry Phillystran. Have you contacted them? One poster on the phillystran-elmers forum on eham.net said only Texas Towers and Burk
I'm curious, Steve, where 1/4" EHS is used in place of recommended and spec'd 3/16" EHS, does one tension the 1/4" EHS to 400 lbs. as one would do with 3/16" or to whatever tension 1/4" is rated for?
Thanks, Frank. Good info. I'm still curious, though. Is there that much slack in 1/4" EHS tensioned to 400 lbs. -- 10% 3/16" strength? Is it the weight of the cable introducing a sag that 400 lbs. te
