Topband: Beverage is down
Hunters took down my bev on the land behind me. Only 250 foot unterminated, did not seem to be working all that great on 160 but really well on 40 and 30 (towards EU), although 2 months is not enough time to evaluate. So I have re-installed the bevs on my property within boundaries, heagin 330 and 210. Unterminated. 150 foot long each. I am thinking results will be better if I terminate. But should I use a resistor smaller than 470 ohms for these shorter bevs? Still hoping the bevs can do the trick, as I don't have room for EWE or K9AY (although I could do a small receive loop).

Topband: Inverted L Lengths
Dear OMs, I note that some use inverted L antennas of 160 feet plus in length and others like myself have them closer to a quarter wave length at 132 feet or so. My antenna runs nearly 100 feet in the vertical and then goes horizontal for about 32 feet. I do not need to use a variable capacitor to tune it the SWR with eight raised radials is around 1.4 to 1 and it performs very well indeed. What is the advantage of the longer wire? In my ignorance it would seem to detract from the vertical element and raise the angle of radiation. Am I missing something? I believe both designs are shown in DXing on the Edge but there is no comparison between them in this book. I prefer not to use a variable capacitor outside though one was purchased in case needed. My radials come from about six inches above ground and slope up to about eight feet above ground supported a few feet from the antenna by four foot high fence posts before going into my wood and being supported by electric fence insulators screwed into trees. Yes I know four radials should do but I am able to put up more and it seemed to broadband the antenna a bit better and the antenna works over the whole of the 160M band though it seldom is used on phone. The band seems very lonely this year but most of my receiving antennas are not yet up due to cattle in adjacent fields. I hope they are soon moved. A Hi-Z 4 square receiving system is on order and this may augment my K9AY and improve the situation. Top band operators are made of sterner stuff than I am as it is so hard to stay up through the night. 73 Doug EI2CN ___ UR RST IS ... ... ..9 QSB QSB - hw? BK

At 150' it is really not long enough to work as a Beverage on 160 meters (a Beverage needs to be 1 x wavelenght long, or more, indeed, 3 to 5 times more). That antenna, however, may still be a good low noise RX antenna, and thus useful. So try it. It sure could be a great RX antenna for 80, 40 and 30 meters. If you have more space, make it longert. If not, lay it on the ground, as a BOG, which can be a lot shorter for a similar pattern, but with lower gain. (i.e. you may need a pre-aplifier).
