In case anyone is interested, the P3i Dipole which is supplied by Pilotawarehardware is also as good if not better than the antenna supplied for the ADS/B (DVB-T) dongle. Depending on how these are positioned could take out the angst of where to site the antenna and actually which antenna goes where. For me now, it matters not which antenna I plug into which socket if we take the PAW out of the aircraft.
On the Pup I have the dipoles on suction mounts high up either side of the windshield out of line of vision, with the cables suckered and then tucked around the coaming. The case for my PAW has been modified as per my original 'beta' version with a right-angle MCX to SMA pigtail through the case and out at the end where the P3i antenna is. GPS is on a Mouse and the PAW is attached to the lower door pillar with Velcro so is out of the sun.
On ADS/B I can see traffic across pretty much the whole of England, across to Southern Ireland so the antenna works perfectly.
Sorry can't post a pic as the PAW is in the aircraft.
