news:xLD8e.2235$lz1.1261@lakeread01: I have been perusing the information on Lightning Protection in the link that you provided. As a side issue, have you studied CAT III Voltmeter protection? http://www.ecmweb.com/mag/electric_m...afety_measure/ Also, being too tired to digest much more information, and having saved the information from your posts, have you ever see this antenna, any comments that you have would be appreciated? http://www.universal-radio.com/catal...wire/4075.html As usual, reading the reviews on EHAM, several were positive, a couple were absolutely negative. It's an end fed antenna that they represent as needing a 25 foot central rise. The reviews seem to talk about counterpoise, though the drawing at the link above seems to be suggesting that the central pillar is the counterpoise, I would guess that it is a network of wires needed to be buried. The 2 legs are 55 feet, to the rise that is, and one of the reviews complained that the actual overall length was longer than advertised. "Also they're saying it only takes 88 feet of space is flat out wrong. If you do simple math it will tell you 97 feet with the 25 foot support. I put mine up to 30 feet and it takes up 92 feet overall." Lastly, I would guess that people should not be exposed to the antenna when transmitting. Alas this would still put me back into the need of a vertical antenna for transmitting with sufficient rise above the yard for safety. http://www.eham.net/reviews/detail/1550 Nevertheless, I am still seeking to improve my receiving antenna for SWL with the addition of lightning protection. Thanks again, Dr. Artaud |
