Hi Ken,
Small diameter "magnetic" loops such as the Pixel can be very effective in nulling a single vertically polarized local RFI source, fortunately most local RFI sources are vertically polarized. Their deep narrow beamwidth null is also very useful for determining the location of an RFI source. A small diameter loop provides no useful directivity for skywave propagated signals (such as the atmospheric noise in VO1HP's video) because the polarization of the incoming wave is constantly changing. 73 Frank W3LPL ----- Original Message ----- From: "Kenneth Grimm" <[email protected]> To: "Bruce" <[email protected]> Cc: "Topband" <[email protected]> Sent: Monday, April 25, 2016 3:25:04 PM Subject: Re: Topband: Pixel vs BOG Wow! The BOG blows the Pixel loop away. The loop sounds like my vertical! I wonder if there might be a feedline problem? Surely the loop isn't meant to be that noisy. 73, Ken - K4XL On Mon, Apr 25, 2016 at 9:55 AM, K1FZ-Bruce <[email protected]> wrote: > Mixed reviews. > > Pixel loop antenna vs 200 foot BOG antenna at VO1HP. > www.youtube.com/watch?v=GTXvcEwgUsU > > 73 > > Bruce-k1fz > www.qsl.net/k1fz/bogantennanotes/index.html > _________________ > Topband Reflector Archives - http://www.contesting.com/_topband _________________ Topband Reflector Archives - http://www.contesting.com/_topband _________________ Topband Reflector Archives - http://www.contesting.com/_topband
