Hi,, I simply clipped the antenna cable close to the antenna and
soldered RG58U (what ever the 50 ohm number is), cable to it! I used a
short piece of the RG58 interior insulation and sloped it to match the
174 to cover the solder connection, then folded the outside conductor,
from each cable, over it, taped it, and waterproofed it!! About 10 feet
went up the pole where the antenna sits,, about 10 feet went through the
attic with about a foot down from the ceiling where it is connected to
the GPS, (GPS is still indoors), then about 30 feet of RS232 to the
computer! I use telephone cable and connectors for the GPS power and
one second data! I get strong satellite signals, even with the cable
Just my two cents worth of experience!!
