I note that the high-quality shielded Cat cables have the drain wire tack soldered to the metal clip at the plug. Sadly, I have also found that "professional" installers often do not even deal with the drain wire on installations in businesses.

Perhaps this helps

Fully operational.... new GPS antenna, sdr.hu listed. Should be ready for TDoA

If you do a full freq look at the Kiwi WF you can often see the chirp sweep go by. I'd like to be able to pick a chirp TX site by name name, Millstone Hill for example, and knowing it's start time, be abe to ID that sweep that goes by. The highest freq seen would indicate the MUF for it at the Kiwi RX site.

it is now http://rx2.wa2zkd.net and is on sdr.hu as well

It's a Pixel. I had not chosen which loop to ship when I configured the Kiwi here at home.

http://142.0.103.74:8073/ is OTA

Here's data I took using the Spectracom GSG-6 Simulator for L1 sats. This compares Kiwi S/N3327 with a SwiftNav Piksi (no antenna, direct connect via DC Block)



Note that the Kiwi has about 15 dB less margin at low levels

My project for tmrw is to use a Spectracom GSG-6 GPS simulator/generator to map actual signal strength at the Kiwi GPS input to reported RSSI. Report to follow

ERP the result of antenna gain I'll guess. Rockwell-Collins has a WBHF waveform that goes to 48 KHz. http://www.hfindustry.com/meetings_presentations/presentation_materials/2012_sept_hfia/presentations/RC_WBHF_UK_Trial_2012.pdf
