[time-nuts] GPS antenna splitter recommendation?

[Robert DiRosario]

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!

Here is a passive 4 port for $100.00 (9 available)

And this seller also has a active 4 port, also for $100. (1 available)

And this one has a 4 port passive for $80

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!! :-)
