Seehttp://web.me.com/geoff.cottrell/G3XGC/Radio_articles.html and select the article A noise reduction receive antenna for 1.8Mhz, I used LDF 4-50 hard line coax which meets the electrical requirements and is very tough weather resistant. I've tried all the other loop type RX ants like Flags, Pennants, etc without any success but this Mag Loop has been a godsend to me and is now my 1st choice, even before the Bevs. It's made all the difference many times over, by gaining a new one or not on TB. It's sited about 150ft from my TX vertical and picks up no detectable noise from it. I can email photos of my interpretation on request. Good Luck Dave G4GED ___ UR RST IS ... ... ..9 QSB QSB - hw?

Topband: progress with the antenna adventures
Hi, I whizzed up an L network to put on my wire after the Murch disaster. Instead of making something more elaborate using my roller inductor, I used a tapped coil (with alligator clips) and a large value dual cap from a broadcast receiver (yes - using low power). I will need either more inductance or more capacitance. Adding a switched in cap seems to be the better idea. I run out cap just when the swr starts it's nosedive. 80, 40, 30, and 20 have clearly defined sweet spots and a few on-air tests are encouraging. The RBN is down at the moment. When it comes back up I'll make use of it to help gage results, too. When I get a handle on the parameters for my network I'll get around to a nicer project with that roller inductor and some *big* caps in a big metal box. That Murch needs a lot of work to ever work with my kind of antennas. Maybe I should offer it in trade for something more useful to me. Is anybody here interested in a Murch 2000B? The paint has started peeling from parts of the cabinet as Murch did not use any primer at all (easy to remedy). I suppose it would be fine as-is for somebody with coax fed antennas that are 50 ohms resistive. It can handle the legal limit and is supposed to cover 160 meters. It even tried to tune my end fed wire but with a T network it was no joy. I'll try using the Murch for some fishing bait before I make radical mods to convert it to an L. 73, Bill KU8H ___ UR RST IS ... ... ..9 QSB QSB - hw? BK

At this quiet location I had to realise that nothing was gained, which was a disappointment ! 73 Rag LA5HE in Telemark Rag, the ALA1530 is not designed to compete with very large antennas like the Titanex V160HD or with other loops with larger apertures. Its primary purpose is to provide low noise reception in a high noise urban environment. The ALA1530 has been providing this sort of service for the past 15 Years. This done by cancelling out the local E -field and providing high immunity to conducted power line noise. Therefore, deploying the loop in a quiet location, the aforementioned features will not be seen. However, if one requires, say more gain or more importantly a higher s/n with a Broadband loop, then a larger loop aperture is required. To this end Wellbrook provides a Medium aperture loop the ALA100M for simple wire loops say 4 to 8m in circumference or the new ALA100LN large aperture loop for 20m circumference antennas. 73 Andrew Ikin ___ UR RST IS ... ... ..9 QSB QSB - hw?
