We built and tested a window line FCP - when it was dry and wet... it was a dismal failure.
Been there, done that and I have three lengths of window line cut and connected together in a 33, 66, 66 section globs in my storage shed. It is available immediately to the highest bidder, shipping and handling at buyer's expense... And... BTW: A loss calculator for wet or dry window line available at: http://vk1od.net/calc/tl/tlc.php >sense. It is well known that window line is >lossy when wet. I am curious if anyone has actually measured this over a range of frequencies. Afaik, the "it's lossy when wet" is based on a model that I've seen some say overstates the loss for a wet window line. > I am feeding my vertical >using 850 feet of open wire line with XHHW >insulation (whatever >that is made out of). XHHW uses cross-linked polyethylene insulation. It is very tough (it's used on triplex-type power lines), and I would expect it to have essentially the same electrical properties as "regular" polyethylene wire since it's very nearly the same chemical composition. > It would be interesting to measure the >loss on a rainy day and see how much it >increased. >Rick N6RK You could probably do a more controlled test just wetting the lines with a garden hose :-) -Bill [Sent using Blackberry Messaging] _______________________________________________ UR RST IS ... ... ..9 QSB QSB - hw?
