I have to make a rather long run from the shack to tower, about 500 feet. This tower will have 2 el 80 + 8/8/8 stack 10 + log periodic covering 30-10. What kind of coax would you run assuming only on
Many thanks to all for your suggestions, recommendations and comments, especially to the person that supplied the loss information for the various types and sizes (sri cannot remember your name). I f
I used one to test the coax running from the com box in the nose to the antenna on top of the vertical stabilizer on an F-106 in 1962. It was also hand operated. The bird was towed into the hangar an
I thought that was a bird. Over on this side of the pond we have double-breasted, red-headed bed thrashers. 73, Keith NM5G Many of us have a w*nch that reels up the bed-sheets... full auto-brake too.
It seems to be well known that planting an antenna over salty water will greatly enhance radiation. Is this advantage in the near or far field, or both. Would installing radials under a tower with ho
Scotch 88 tape works for me. If you want to protect completely against water vapor, coat the Scotch with liquid tape and apply another wrap after it dries. 73, Keith NM5G I had a Ham IV rotor service
I agree about Scotchkote being hard to remove. That's why I put on two layers of 88. When it comes time to disconnect, just remove the outer layer, scrape off enough of the Scotchkote to get to the i
This reminded me of another option. Lately I have been using one layer of 88 and another layer of rubber fusion tape. This is the tape used to seal the fiberglass joints on a SteppIR Yagi. I purchase
I got the GB HTP-1010 from Home Depot via the Internet: http://www.homedepot.com/prel80/HDUS/EN_US/jsearch/product.jsp?pn=100069055 These are 10 foot rolls for 4.98 + shipping. I bought 4 rolls which
I have a 200 foot Rohn 55G that will be going up in the near future. On this tower I want to put a stack of three 3el 40M and a stack of three 7el 15M Yagis. One of the 40M antennas will be at the to
Thanks for the info Frank. That's what I was looking for. After other similar posts I have decided to go with two 40M Yagis and 3 or 4 10M Yagis on that tower. I will put the 15M Yagis on a separate
I like to use Scotch-Brite as a plug. It breaths well, is built for moist applications and bugs apparently hate to crawl on or through it. 73, Keith NM5G I had forgotten bout that form of protection
I would not use it for mast material. You want something like high carbon steel or 6061-T6 aluminum. Steel is about twice as strong as aluminum in the same OD size and wall thickness, so it is the be
I know Larry. He visited me at my QTH recently. My antennas are located about 1/4 mile from towers with 12 138KV lines. Noise from these lines has never been a problem since 1999 when my 150 foot tow
Gregg, You have made a broad generalization out of your observations. Initially it seems like a logical conclusion, but there are observations from other locations that are entirely different from yo
The C-31XR has coils? 73, Keith NM5G Mark I had one up for a couple of years, it worked fine on 20 and 10 but it was very narrow on 15. I paid for some new(different) coils to no avail. They kept tel
Two words come to mind: Resourceful Thrifty 73, Keith NM5G I have read and heard this countless times and often in a "bragging" manner! Is this the image that we hams should be promoting? Consider th
One should be able to find a good used tower (with guys and other hardware), rotator and tri-bander for about 50 cents on the dollar compared to new price. Let's say it is 70 feet of Rohn 45G with Fo
Well, I did leave out a few things. But $1500 for a tribander is overkill. You seem to have pulled your figures out of your hat. The ones I listed are current prices. Also, someone commented off-list
I have some used Phillystran and want to use it again to put up a new tower. Is there any advice on inspecting and testing it? 73, Keith NM5G _______________________________________________ _________
