MCX to TNC cable type?
I have a Jupiter GPS receiver that I am using to build into a 10MHz GPSDO.
The receiver is supplied with a passive 1.5GHz L1 antenna and a short (150mm) cable to join between the antenna and the receiver. I wish to mount the antenna outside my shack/shed/workshop (please highlight your preferred name). The antenna has a female TNC connector, the receiver has a female MCX connector. I think that my attempts to make a weatherproof enclosure for the receiver would be less successful than making a longer cable but I'm a little daunted by the thought of terminating the tiny co-ax to the MCX so does anyone have a clever idea? I'm considering a 50Ω extension with a TNC on each end....

A quick search found loads such as https://www.unmannedtechshop.co.uk/p...v=79cba1185463

Weather proofing and water proofing are two very different things. Take a house, nice and dry inside and it has loads of holes in it. |

Re: MCX to TNC cable type?
Second thought, my GPSes work well indoors (Garmin walking types) and very well next to a window. And getting a frequency "fix" is a lot less difficult than a position fix.

Re: MCX to TNC cable type?
I'd use a TNC male to female lead to extend the existing cable to the length you need. That was my solution to exactly the same problem when building a Jupiter module based GPSDO.
It has the advantages that all the delicate bits can be kept within the GPSDO enclosure and you can use the co-ax of your choice for the run to the antenna. It's worked well for me for the last 10 years or so. Hugh |
