Re: Topband: COAX CABLE
One reason to use RG6 for burying, is that it is a lot easier to bury across lawns, etc. You can push it into a notch (as opposed to a trench) and just step on it. It's out of sight, and undetectable after the next rain and lawn mowing. 73, Guy.

Re: Topband: RG6 coax questions
"Probably" is, somewhere, at some price, and possibly with minimums. The RG6 style is sold in huge quantities, really a default feedline for many things. Digging required, unless you're lucky and someone has seen it. The digging required is part of the PITA. And with that many shields, whose tools and connectors? Looking to use it as a feedline on 160 I take it. 73, Guy.

Topband: Pixel Technologies Magnetic RX Loop – any users out there?
I have been considering buying a K9AY antenna but can only have it up during the late fall through spring. There is no way I can keep it up all year is because it would have to be in my backyard a nd I would need to cut the grass where it is installed. Down it would have to come every spring. So I recently saw an ad for the RF PRO-1A in QST and thought that thought that it might be a decent RX antenna for my situation that I could keep up year round. Would mount it on the side of my house and turn it with a cheap rotor. http://www.pixelsatradio.com/PDF/RF_PRO-1A_Cut_sheet.pdf It would be used in conjunction with my Flex-5000, a SteppIR BigIR for 80-10 and an inverted L for 160. Since my Flex-5000 has diversity RX my thought was that using the RF PRO-1A and one of my TX antennas would be a good combination. So my question is are there any RF PRO-1A users on the list and if so what do they think of the RF PRO-1A on 160? 73 Zack N8FNR ___ UR RST IS ... ... ..9 QSB QSB - hw? BK
