Hi Mike, I wanted to try and raised similar question in 2011:
http://lists.contesting.com/archives//html/Topband/2011-04/msg00027.html It was some theoretical discussion but no practical experience, so I decided to try myself. It was temporary installation for 1 weekend, so use regular indoor CAT-6 cable, two reversible Beverages made from same cable and one such cable (200 m) used as feeder. All pairs used at "feeder" - 2 pairs for one Beverage front and back, other 2 pairs - for other. Load resistors - at direction switch at radio. All cables were laying on grass- sort of 20-30 cm up from the soil. Worked very good to my understanding in middle of summer QRN conditions. Short story is here: http://lists.contesting.com/archives//html/Topband/2013-02/msg00148.html In your case - BOG has much lower output even to my Bev on grass - so it much more sensitive to noise pickup. Together with not always predictable BOG behavior - see all BOG related posts in this mailing list. 73 GL Arunas, LY2IJ 2020-05-17 23:19, Mikek rašė: > Did a first test on a BOG, I noted it didn't have a f/b ratio. > Then I noted I connected the wrong pair to the radio. > That means the twisted pair is picking up signal. > I terminated it hoping that would quiet it, It didn't. > I corrected the wiring error, But the feed line pickup > makes the BOG useless. > > On a previous BOG I used #18 twisted speaker wire and it > picked up very little RF when connected the the radio. > > Do I need to do anything with the unused pairs, > that would help? > > Any thoughts on how to prevent RF pickup by the feed line? > > Mikek KF4ITA > _________________ > Searchable Archives: http://www.contesting.com/_topband - Topband Reflector _________________ Searchable Archives: http://www.contesting.com/_topband - Topband Reflector
