I'm away from Friday, I may have some time tomorrow to test further, but I'm not sure as I need to pack and depart at 4am... Otherwise I'll test again when I'm at home.

All I did was unplug it and plug it in again in another room... I'll have to check but the will to live walked out a few minutes ago and I went to the fridge to get a beer...!!

Yes negative, I was just making it easier to read...
Starting to lose the will to live with this... I can only get a reading off the long one (that comes standard) if I hold the tip with my fingers.

JCurtis, I think you make the combined board with the thingy soldered onto the board direct with the baro thingy... that one is the master... I'm working on getting one back up and working.

Ah... when i say horizontal, I mean tip to tip, not broadside to broadside.

Long: https://www.wirelessthings.net/868-915-mhz-rubber-duck-antenna
Short: https://www.wirelessthings.net/868-915-mhz-small-rubber-duck-antenna
Adapter: http://r.ebay.com/HPKFIv
I was surprised the adapter made a difference... I also think I've buggered one of my ARFs as it doesn't seem to be responding now...

I did some highly scientific testing tonight... 
Tests
10ft apart
No aerials on either - IS 77 IM 70
1 stubby aerial horizontal – IS 88 IM 57
2 stubby aerials horizontal – IS 69 IM 41
2 stubby aerials 1 hoz 1 vert – IS 65 IM 35
2 stubby aerials vertical – IS 52 IM 23
1 stubby, 1 long both vertical – IS 46 IM 23
2 stubby vertical + adptr - IS 75 IM 47
I couldn't get two long aerials to work... not sure why, but does this mean that 2 right angle adapters (in my last example) would be pretty poor? Seems to be worse that 2 stubby aerials horizontally.

« on: October 27, 2015, 03:48:18 am »Would a short cable run between the PA unit and the aerial cause any serious drop in signal strength do you think?Not much, but don't see much evidence that testers are using ground planes, which are an essential part of the antenna system. With a remote antenna it would be more important.
Ground plates for which antenna? I understand it'll help the ADS-B side (but that's not a problem, airborne I can see planes up and down the whole country), would it help the ARF?

me neither... aside the groundspeed, but I would often get that at home with the built in GPS on the ipad (1 or 2 kts).
the only issue I did have was when it went a bit crazy on me, see this post: http://forum.pilotaware.com/index.php/topic,191.msg2714.html#msg2714

I still wouldn't be able to get it on the coaming due to the slant of the windscreen. I've ordered 2 right angle adapters, I'll get them set up at home and see if there's any loss in using them.

I would agree on B and C, no green flashing light, no GPS info - took me a while to remember that when I got mine!! I've had the GPS dongle plugged into various USB ports so I would discount A.
Also, the ipad has assisted GPS, which can use wifi and cellular services to triangulate your position, giving you a much quicker time to first fix than just a GPS dongle, which needs to see the satellites..., also why it works exceptionally well indoors.

I'm going to set them up one night this week and test the RSSI (or whatever it is called) with the two different aerial types in master/slave mode.
So considering mine was horizontal and Bryan's was vertical and we got 4nm, that's not too bad then!!
