[QUOTE="Vipersan, post: 972011, member: 325666"] So ...had to at least try it ..even though it's not on a dish ...and the wrong polarity.. pointed roughly in the direction of Inmarsat at 15.6W .. Indoors and behind glass .. Of course this _could_ just be random PC noise ...? but what I can tell you is .. No LNA involved .. It is directional ... It does disappear when the antenna is disconnected from Airspy .. It is roughly in the 1.5ghz range So ...I'm assuming that the helical is at least 'tuned' to the right band.. here is a pic of the antenna balanced on the telescope angled upwards .... ..and a screen grab of ...errr ...some signal spike in the right region which is about 5db above the noise.. rgds VS[ATTACH=full]93416[/ATTACH] [ATTACH=full]93417[/ATTACH] [/QUOTE]
