Guys, on this subject, we put together and qualified a convenient and complete (fairly) low-cost timing-compatible GPS antenna kit that includes all the mounting materials, 150 feet of cable, all the connectors, and down to the last screw, nut, and bolt everything one would need to mount the antenna. Only standard tools are required for the installation. Compatible to any L1 GPS receiver, works from 2.5V to 5V. We get up to 52dB C/No with 150 feet of cable on our uBlox GPS receivers with this antenna, and the antenna cable length can be easily extended with F-connectors on both sides. This was done because so many people had problems getting all the parts to put an antenna together and called us for pointers to antenna kits (which we could not find), and we went out and bought all the different pieces needed to do so and put these together as a kit. Check out the _www.jackson-labs.com_ (http://www.jackson-labs.com) website if interested. 10% Time-Nuts discount (one unit per person) - $241.20 per kit w/o the lightning arrestor. A bit more pricey when the antenna lightning surge protector is included which is mandatory for any outdoor installation. I know this is more than what you would pay for a used antenna on Ebay, but we are not really making any money on this, we are pretty much selling it as a convenience to our customers. Please contact us off-this-list if interested. bye, Said In a message dated 2/5/2014 09:46:27 Pacific Standard Time, n1...@dartmouth.edu writes:
As has been discussed before, a splitter intended for home satellite systems is a cheap solution as they have the bandwidth and the DC pass required. I have one between a couple of Thunderbolts. It powers the antenna and shows antenna OK on both. Using a splitter is better than just a T as it does lend some isolation between the receivers.

So to limit the growing number of boxes, I want to put two Resolution-T SMT receivers in one box, sharing power and antenna inputs. My question is " How best can I share the antenna input, minimizing any interference between the receivers?" . Will any interference matter? For example, I can easily connect three bits of shielded coax in a "Y" , but will probably get reflections from each receiver. As the cables will only be about 15cm long, would it matter? How about the DC antenna supply? The antenna DC will NOT be powering an antenna as it passes through a DC blocked splitter used to share an antenna between most of my receivers. I might be able squeeze a Mini-Circuits splitter in the box and DC-block both outputs but that may be overkill. What discrete circuitry might be a replacement? Will the "Y" do it? >>> >>> Someone must have already succeeded with this type of config. >>> >>> Thanks in advance for your input. >>> >>> Regards, >>> Mike >>> >>> >>> _______________________________________________ >>> time-nuts mailing list -- time-nuts@febo.com >>> To unsubscribe, go to https://www.febo.com/cgi-bin/mailman/listinfo/time-nuts >>> and follow the instructions there. >> _______________________________________________ >> time-nuts mailing list -- time-nuts@febo.com >> To unsubscribe, go to https://www.febo.com/cgi-bin/mailman/listinfo/time-nuts >> and follow the instructions there. > _______________________________________________ > time-nuts mailing list -- time-nuts@febo.com > To unsubscribe, go to https://www.febo.com/cgi-bin/mailman/listinfo/time-nuts > and follow the instructions there. _______________________________________________ time-nuts mailing list -- time-nuts@febo.com To unsubscribe, go to https://www.febo.com/cgi-bin/mailman/listinfo/time-nuts and follow the instructions there. _______________________________________________ time-nuts mailing list -- time-nuts@febo.com To unsubscribe, go to https://www.febo.com/cgi-bin/mailman/listinfo/time-nuts and follow the instructions there.
