I just went on ebay. I got one of the 8 port units with 5V antenna power supply and 11 db amp, there is still one left $175.00 https://www.ebay.com/itm/GPS-SOURCE-S18-A11-P110-5-GPS-1x8-WAY-SPLITTER-DEVICE-LOOK-REF-233G/193397441449?hash=item2d0762c3a9:g:PQIAAOSw0eNdDSLi Here it is in the catalog at $1064. !!!! $175 used looks like a very good price! https://www.gpssource.com/products/s18-1x8-standard-gps-splitter?variant=10811989699 Here is a passive 4 port for $100.00 (9 available) https://www.ebay.com/itm/GPS-Source-1x4-Stamdard-Amplified-Splitter-S14-S14S-E-SF/401835679864?hash=item5d8f45e078:g:pkYAAOSwfe5dRKrq And this seller also has a active 4 port, also for $100. (1 available) https://www.ebay.com/itm/GPS-Source-1x4-Standard-Amplified-Splitter-S14-S14S-A-E-HS-SF/401835678023?hash=item5d8f45d947:g:zOcAAOSwcyNdRKns And this one has a 4 port passive for $80 https://www.ebay.com/itm/GPS-Source-1x4-4-Way-Splitter-Slimline-PN-S14S-SF/124166494822?hash=item1ce8e65a66:g:aPkAAOSwXZBepQkG A couple in Israel also show up. I just did a search on "gps source". Someone has a 10 dB GPS attenuator for $100. At 1.5 GHz some RG-58 will do that for a lot less money!! :-) Robert On 04/30/2020 04:13 AM, Larry McDavid wrote: > Frank, I'm using a GPS Source S14WI 4-way GPS splitter.
