I am wrestling with what to get to replace my 15 year old KT34A, which has been an excellent antenna, but is getting long in the tooth. I'm also thinking about having 17M and 12M capabilities on the
The string on 9913 has been very interesting. I have a major recabling project to do this summer, and am debating what coax to use for the runs to my tower (150 feet or so, 1HF, 1 6M, 1 2M beam). The
Where do you find this "flooded heat shrink tubing." First I've heard of it. By the way, thanks to the persons who responded to my question. There is an amazing wealth of information being passed aro
I have used it, with large rotor loops, and it's done well. My cable is over 15 years old now, and in need of replacement, which is no surprise. I do not use coax arms down the tower, I only use one
I'm refitting my rotor, and have rotor cable that's 18 years old but seems to work just fine. The "outside" run looks to be in good shape (a bit "dirty gray" in color, otherwise it appears sound), an
I also noted the same seller has some "regular sized" (.405) cable available (black, 1000' spool): http://cgi.ebay.com/ws/eBayISAPI.dll?ViewItem&category=3704&item=5702721 421 Specs are here: http://
I had a Heights 64 foot crankup with an electric winch from 1980 through 1986 (pre-insolvency manufacture). The tower collapsed into itself when the steel rollers bound on the aluminum legs, and the
I have a Tri-Ex Sky Needle, a TM-358 (58'). it's a great tower. I would love to find a 70-footer (TM-370 or TM-370HD, which was the same size as the TM-390 (90') minus the top section, and quite rare
The ordinance says that "This article shall not govern any tower, or the installation of any antenna: (i) That is under seventy (70) feet in height; and (ii) Is owned and operated by a federally-lice
I recabled my antennas (HF, 6 and 2M) recently with Davis RF Bury-Flex. Great stuff, it's flexible, tough jacket with good UV resistance, low loss, and easy to work with. Plus you can direct bury it
I would love Robertson's address, I would like to write him with the history of property values in my neighborhood over the last 16 years I've had my tower. Values are up 100-150%, which is just betw
Some reviews on eHam.com note noise issues with the AlphaSpid controller. Here are some quotes: NOISY - on 50MHz and on 144MHz !! Control box: yes, generates noise on HF (signal sometimes 9), but not
I've found the folks at SteppIR more than helpful. I had a motor failure shortly after installing my 3-EL. Mike, K7IR, spent aver an hour with me on the phone, and lots of email time afterward, runni
In addition to Tashjian, would also be curious to hear about US Tower experiences. I have been trying for over 5 weeks to get some wind loading calcs done by the engineer UST uses (not an employee, u
The fellow is UST's retained engineer. When I asked UST about the wind load of my proposed antennas (not just 1 foot above the top of the tower, for which the towers are rated, but several stacked an
Here's a good article that should help. http://www.ifwtech.co.uk/g3sek/stacking/stacking2.htm Lou, WØFK Hi all, I have a 4-element 10 meter beam for my tower. I also want to put up a 6-meter beam, an
I sent this link in reply to another similar question a couple of days ago. http://www.ifwtech.co.uk/g3sek/stacking/stacking2.htm Issue is not interference with the SteppIR from the VHF/UHF, but with
Greg, what's the diameter of the tubing? The TM358 is 22'4" retracted, tube sizes 2-7/8", 4.5", 6-7/8". 58' extended. The TM370 retracted is 27'-3", so it what you have available sounds like a TM358.
Absent an engineering analysis that what you're proposing will be adequate, and that the streeses from the guys won't compromise the structure, I wouldn't deviate from the manufacturere's engineered
Tashjian's voicemail seems to be Karl's cell phone, and my experience has been that returning calls is low on Karl's totem pole. Emails can also be problematic. I suggest you call back several times
