On reason is that the running the twisted pairs through standard preinstalled lightning protection barriers is trivial, whereas certifying and finding space for a suitable lightning barrier for coax is a lot of work. Another advantage is that you can reuse existing cabling in rented buildings, instead of paying sometimes unbeliveable amounts to run your coax to the roof. (One of the main reasons Telecome Cesiums are still a thing, is that they often are much cheaper than renting space for a GPS antenna on the roof and cabled down to your kit in the basement.) However, one downside is that the PPS signals may suffer from tempco on the order of 1 µs/K. -- Poul-Henning Kamp | UNIX since Zilog Zeus 3.20 p...@freebsd.org | TCP/IP since RFC 956 FreeBSD committer | BSD since 4.3-tahoe Never attribute to malice what can adequately be explained by incompetence. _______________________________________________ time-nuts mailing list -- time-nuts@lists.febo.com -- To unsubscribe send an email to time-nuts-le...@lists.febo.com To unsubscribe, go to and follow the instructions there.
