While we are on the subject of coax..... Does anyone have any experience with FXL-780 as a Heliax replacement? http://www.rfparts.com/heliax_AVA5-50.html It is made by Andrew, and is as low if not lower loss than AVA-50..... Does anyone know of why we would want to avoid the FXL-780? Thanks and 73,Joe kk0sd
