Re: [Elecraft] [SECC] Mosley TH-3jr Weirdness
NoAlOx is available at Home Depot and probably many others, excellent suggestion, highly recommended. 73, Jim - Original Message - From: Timothy Raymer timothy.ray...@mdc.mo.gov To: Rich Arland k...@live.com; Elecraft Reflector snip..

Re: [Elecraft] [SECC] Mosley TH-3jr Weirdness
Rich, Suggest you look into silicone hose repair tape for the coax connection. Electrical tape tends to unwrap and/or leave a messy residue. This stuff can be found in the garden hose section. It's a bit more expensive, but does a great job. I've wrapped my Steppir Boots with it, great UV protection. NeverSez (sic) or aluminum wiring protection goo found at an electrical supply house will work. There's copper based stuff that is marine grade and used on thing like propeller bolts that will work well too. Wear gloves or have rags around, it's messy and will stain. I wouldn't bother cleaning the whole element, unless you're going to paint them (or powder coat). They'll oxide again. From street level you'll never know either. Don't forget to protect the joints and hardware on your Glenn Martin as well. See ya on da air... 73, Julius n2wn - Julius Fazekas N2WN Tennessee Contest Group http://www.k4ro.net/tcg/index.html Tennessee QSO Party http://www.tnqp.org/ Elecraft K2#4455 Elecraft K3/100 #366 Elecraft K3/100 -- View this message in context: http://elecraft.365791.n2.nabble.com/Mosley-TH-3jr-Weirdness-tp6631788p6634459.html Sent from the Elecraft mailing list archive at Nabble.com. __ Elecraft mailing list Home: http://mailman.qth.net/mailman/listinfo/elecraft Help: http://mailman.qth.net/mmfaq.htm Post: mailto:Elecraft@mailman.qth.net This list hosted by: http://www.qsl.net Please help support this email list: http://www.qsl.net/donate.html
Re: [Elecraft] [SECC] Mosley TH-3jr Weirdness
OK, Gang!!! I stand corrected...this is a Classic 33!!! And several of you have told me that this is a capacitive feed system that works very well. I will yield to the expertise to the group. Don't know why I decided that it was a TH-3jrsynapse lapse OK, we are on the right track now, folks!! I am going to scrub the aluminum and get it looking purty so when it goes up in the air I can point up to it and say, That is my antennathere are many like it but this one is mine!! (any Gyreenes in the crowd??) At any rate, I hope to have this puppy in the air by the end of this weekend, God willing and the creek don't rise. I need to get the Glen Martin roof tower in place and secured to the rafters, but that is relatively small potatoes compared to getting the Yagi up in the air. Thanks to all who replied. If any of you have any further ideas/suggestions please don't hesitate to e-mail me pronto. All suggestions/ideas are gratefully accepted. 73 Rich Arland, K7SZ Bent Dipole Ranch, Dacula, GA Cogito Ergo CQ (I think therefore I HAM) Author: The ARRL's Low Power Communications, the Art and Science of QRP (all 3 editions) Editor: QRP POWER, QST Magazine (Jan 2000 to Dec 2003) Editor: The Learning Curve, CQ Magazine Editor: The Beginner's Column, CQ-VHF Magazine From: k...@live.com To: noga...@yahoogroups.com; s...@contesting.com; se...@contesting.com; g...@yahoogroups.com; elecraft@mailman.qth.net Date: Thu, 28 Jul 2011 20:03:48 -0400 Subject: [SECC] Mosley TH-3jr Weirdness H Gang: I have a very strange request for info. I inherited a Mosley TH-3jr tri-bander from Russ, AE4NY. The driven element has two (2) 7ft 3 inch pieces of multi-strand wire (NOT coax) in a very heavy insulation running from the SO=239 down each side of the driven element. I have never seen this before. The length does not equate to any ham band covered by the antenna (it covers 20/15 10M). As near as I can tell each piece of wire sits inside the aluminum tubing and the is connected to the coaxial connected but for what purpose I haven't the faintest. So, anyone have an idea as to why this insulated wire sits inside the DE on this tri-bander?? I have photos that I will send to anyone who wants to have a look. I don't want to attach them to this mssg as it is going to several lists. Any info or ideas would be of help as this antenna is due to go up in the air hopefully this weekend. Pls reply off list.

Re: [Elecraft] [SECC] Mosley TH-3jr Weirdness
Rich, Wrap the ends of the wire (Actually Coax Center Conductor) with Electrical tape. As antenna hangs in the heat and cold and does the antenna thing, the insulation will migrate, leaving a small stub of copper conductor sticking out. And it is possible to get arcs off of it if you don't insulate it. Also, there is some special goop that you coat the aluminum with after you brighten up the joints. I think you can use Penetrox or NoAlOx, but the folks on the Elecraft list can better enlighten you. Also, the folks at Mosley can enlighten you with more information: http://www.mosley-electronics.com/page%20files/home.htm Between your Mosley Classic 33, and the Glen Martin Tower, we appreciate you doing business with Amateur Radio suppliers from Missouri! 73 de KA0OUV -Original Message- From: elecraft-boun...@mailman.qth.net [mailto:elecraft-boun...@mailman.qth.net] On Behalf Of Rich Arland Sent: Thursday, July 28, 2011 20:16 To: North Georgia QRP Group; SECC; South East DX Club; Gwinnett ARS; Elecraft Reflector Subject: Re: [Elecraft] [SECC] Mosley TH-3jr Weirdness OK, Gang!!!
