I had a 4-port GPS splitter, but sold it. I got mine from eBay. It was an
HP unit and I got it cheap. You need to watch for a good price on eBay.
I see two HP 4-way splitters on eBay for $73. Search for GPS distribution.
As for the antenna, I use an HP timing antenna. I see some Nokia timing
antennas for $25 on eBay.
