A few people have suggested the Wellborn 1530, but it looks a bit
cumbersome. I have 2 other options with a wire antenna. Check out the diagrams I made and let me know if any of these are feasible and if so, what my best bet would be for this type of application. I sincerely appreciate all feedback. The 1530 is definitely still an option that is available to me still... would it still be better than one of the below setups?

There are to many variables in a situation like this to know for sure which will work better so you will just have try them. -- Telamon Ventura, California |

In the main you will be picking up signals broadside to the wire and not off the ends. Which ever you go for your main problem will be electrical noise and harmonic hash from the equipment in the building (TV, computers, modems, etc.), if it has a metal roof all the better! Get or make a decent ATU - cheap on eBay - and get the wire as high above the ridge as you can. Use a balun designed for a wire antenna and feed from one end with co-ax Create a decent RF ground. (There's plenty of info around if you use Google.) I live in a first floor flat in the south of England and using a wire antenna and ATU I have heard amateur stations from Central & N. America, Australia, N Africa, Asiatic Russia & Mauritius in recent months. Charlie -- www.wymsey.co.uk |

On their site it says it transmits 5,000 watts on 930 khz, but I see no towers at the radio station. I also live a few miles from some microwave towers, and (assuming) cell phone, VHF/UHF TV towers. I am not very technically savy, and would prefer to buy an antenna that is already built. I can assemble it fine and put it up. IN am however very good with diagrams. Size is not much of an issue as long as its not a tower or 10 foot or higher vertical antenna. I'm the manager of the apartment community I live in, so I can bend the rules a bit in terms of roof installation antennae. I'm hearing rave reviews and numerous suggestions about the Wellbrook ALA-1530, but the cost is a big downfall. I tried to post this earlier but google ate it. I had a chance to test a ALA-1530 for over a month. I was very unimpressed. The WL1030 worked at least as well and can be built for much less green stuff. www.wl1030.com The only hard part to find is the Litz wire. And in truth I couldn't tell any difference between solid, stranded and litz wire in this application. I am not a fan of loops and continue to be impressed by the loyalty of true believers. If, as the manager, you could cheat a bit more, there is a 15' relay switched antenna that works very well. http://www.kongsfjord.no/ Look in "The Dallas Files"; "LW-MW-SW Relay Tuned 15' Noise Reducing Vertical Antenna", It does require at least a 4' ground rod 6 to 8 work much better. While I have always been a fan of coax feedlines, I have to admit that for this antenna balanced feedline, either Radio Shack speaker wire or AC zip cord, worked slightly better then coax. Other good antennas could be any of Dallas Lankford's active antennas. The new comp pair is very very good but rather difficult to setup. The next best is "Some of My Favorite Small Antennas for MW and LW", set up is straight forward, but the Crystalonics FET is pricey. The much less expensive antenna in "Low Noise Active Antenna AC/DC Power Supplies" is a very good active antenna. When configured as a active dipole it is a very good performer and only usuitable (IMHO) in very strong MW signal locations. To the best of me knowledge there are no commercial versions of any if these antennas. A friend built the 15' relay switched and used very inexpensive radio shack 12V relays that he sealed with GE "silicon seal". And if none of these look interesting be inventive. Do you have a wood fence? Run wire that blends in as high on the fence as possible. Do you have access to the attic, if there is one, you might try to run wire along the peak, or form a quasi dipole. Are there "tall" trees close to the building? If so then run some wire up the side of the tree. Works best where there aren't kids, they tend to find and pull stray wire off. Terry |
