Chris-- The 58532A is somewhat higher gain (30dBi or better) than most mag-mount antennas (26dBi typ IIRC). The pointy nature of the 58532A also serves as an avian deterrent, reducing the accumulation of attenuating deposits...
Running two receivers, I would highly recommend a real GPS distribution amp such as the 58535A. Such a beast will let you run both receivers from one antenna, while providing isolation between the receivers. I just happen to have one handy, having recently pulled it out of service and replaced it with a 4-port model to better support my time-nuttiness. Contact me off list if you would be interested. 73 Bob [email protected] On Jul 16, 2012, at 16:01, [email protected] wrote: > Message: 1 > Date: Mon, 16 Jul 2012 14:59:52 -0700 > From: Chris Hoffman <[email protected]> > To: [email protected] > Subject: [time-nuts] XL-DC Antenna Requirements > Message-ID: <[email protected]> > Content-Type: text/plain; charset=us-ascii > > All, > > Though somewhat outmoded, looking forward to starting my own time shop with > two XL-DC controllers that I have been lucky enough to pick up recently. > > My question: Do I really need to invest in the likes of the HP 58532A > antennae, or will my surplus Trimble magnetic antennae -- magnetically > attached to a random ferrous backplane -- do? > > I guess what I am really asking: what are the relevant antenna design > requirements here, and does the advent of as 32-satellite-constellation have > any effect upon the antenna choice (i.e. design downgrade) for the TrueTime > XL-DC? > > -CH > > Chris Hoffman > [email protected] > http://ar.ctur.us _______________________________________________ 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.
