[time-nuts] Connector help?
Before I got my multi-band splitter/amp I was using a HP-58517A 8 channel unit. It worked reasonably well with GLONASS and BEIDOU L1. GLONASS signal was a bit degraded and you would lose a few satellites. I could even track GPS L2 with an Ashtech Z12, but the L2 carrier phase / pseudorange data was rather iffy and getting a good L1/L2 position solution was rather difficult. --- >Since the HP splitter will knock out everything that is not right on top of >GPS, are you sure you want to go that route? ___ time-nuts mailing list -- time-nuts@lists.febo.com To unsubscribe, go to http://lists.febo.com/mailman/listinfo/time-nuts_lists.febo.com and follow the instructions there.

Hi Yes I know, this is beating a dead horse ….. Since the HP splitter will knock out everything that is not right on top of GPS, are you sure you want to go that route? Yes it does depend a bit on the antenna. If it’s one of the telecom / narrowband gizmos then the splitter will not have much affect. I tend fo find that in a lab setting as broadband a feed as possible is a really good idea. You never really know what will pop up on the bench next.

My mistake, I have a 58516A in my hand and it does look like an SMC Cheers; Tom Knox "Peace is not the absence of violence, but the presence of Justice" Both MLK and Albert Einstein From: time-nuts on behalf of Clay Autery Sent: Sunday, January 27, 2019 3:52 PM To: martin.fl...@compdecon.org; Discussion of precise time and frequency measurement Subject: Re: [time-nuts] Connector help? It is an SMC connector. Hard to find and expensive, but worth it to insure that the DC power to the splitter doesn't get accidentally hooked to a signal I/O.

Hi Bob, Antenna is a PCTEL GPS-TMG-HR-26NCM ( 26 dB gain) antenna that feeds a Polyphaser 095-0927T-A protector using 1/2 Super-flex. The HP 095-0927T-A would be downstream of the protector with about 100 feet of additional super-flex. Martin On 1/27/2019 5:17 PM, Bob kb8tq wrote: Hi Yes I know, this is beating a dead horse …..
