The thunder bolt specs an antenna to use with it. I don't have the manual with me, but it is more like 34db. I found a HAG-240 marine antenna in a surplus shop for $15.

What signal level is the Thunderbolt expecting? oes it want a 24dB antenna or more or much less? 2) I want to feed two GPS units with one roof mounted antenna. I figure that splitters are just a transformers and will not pass DC to power the antenna. There must be an easy way around this. 3) Do people really run coax straight from a GPS antenna into their house with no protection from lightening? Maybe a GPS antenna is a small target compared to a 100 foot wire antenna in Florida -- ===== Chris Albertson Redondo Beach, California _______________________________________________ time-nuts mailing list -- [email protected] To unsubscribe, go to https://www.febo.com/cgi-bin/mailman/listinfo/time-nuts and follow the instructions there. _______________________________________________ time-nuts mailing list -- [email protected] To unsubscribe, go to https://www.febo.com/cgi-bin/mailman/listinfo/time-nuts and follow the instructions there.
