Cable question: I assume that won't be the problem. I use my 26dB Trimble timing antenna with RG-213 because of the low loss (and the low cost). Before that I had 15 m (45 feet) of RG-58 combined with a car roof magnetic patch antenna in use without any problem. Any 50 Ohm cable can be used, just mind the attenuation. Any combination of those cables will do. Some of the time nuts even recommend cable-TV cable (75 Ohms) due to low loss and good shielding capabilities.
I'd rather take care with the connectors since this can be a great source of trouble, so avoid too much connectors on the signals way down to your shack and use appropriate and well-assembled quality connectors. The slightly higher cost will pay off. After decades of using and assembling every type and brand of connector I can assure you, this is the main thing.

Hi TimeNuts, What are people using for surge arresters between your GPS receiver and the antenna, at the entrance to your house? I've got an entrance panel set up for HF, with copper ribbon to two ground rods. I'd like to add a connection for my GPSDO. I know the frequency is about 1.6GHz, and the active antennas use 5V or less... is that correct? What are the parameters I should consider when selecting an arrester? An associated question, also, if I may: Does it matter if I use different types of cable between the antenna and the entrance panel and then entrance panel and the GPS receiver? Thanks for your guidance, Peter K1PGV _______________________________________________ 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.
