[QUOTE="John, post: 1003693, member: 175005"] Understood, the crude attempt with the foil was to do a bit of quick RF shielding and was wrapped around the plastic SSA device box as well in case it was radiating from there but in actual fact removing the foils made no difference at all. The only thing left un-screened at test time was the usb interconnect lead to laptop & the laptop itself. The coax link from the lnb was WF100 about one and a half metre length with Thomas & Betts Snap N Seal connectors. When the weather perks up a bit in a month or so's time i'll re-do the experiment with the RF source SSA device/ usb lead / laptop four metres or more away from the dish set-up with a WF100 fly lead to connect to a better RF shielded waveguide & probe to see what that set-up produces. Also ..... after i have given up doing the above i'll set up my spare 1.2 Precision solid PF with my spare Ka XMW 21GHz lnb on it looking at a designated freq on 7°E or whatever and take some readings off the Promax ..... Then afterwards, set up my spare fibre CM1.2 with the same tackle and just get some simple comparison readings. Keeps me off the streets i suppose. [/QUOTE]
