[time-nuts] XL-DC Antenna Requirements
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 cq.k...@gmail.com http://ar.ctur.us -CH Chris Hoffman cq.k...@gmail.com http://ar.ctur.us ___ 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.
Re: [time-nuts] XL-DC Antenna Requirements
Hi Chris; There were a number of XL-DC produced with 12vdc antenna power and should be marked near the connector. There are also some marked Down converter required. Other then then those the 58532A is a great choice andf sold under a number of names such as VIC-100, the Lucent antennas are also nice. The lucent are available in three gains 20, 26, 40 dB version. Most are the 26dB version and are a great product. Placement can be important, and although you could use indoors it will perform best as low as possible with a full view of the sky. (Low to avoid terrestrial interference).

Re: [time-nuts] XL-DC Antenna Requirements
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 k6...@arrl.net On Jul 16, 2012, at 16:01, time-nuts-requ...@febo.com wrote: Message: 1 Date: Mon, 16 Jul 2012 14:59:52 -0700 From: Chris Hoffman cq.k...@gmail.com To: time-nuts@febo.com Subject: [time-nuts] XL-DC Antenna Requirements Message-ID: 0208b173-9f7b-49b9-ae83-ee231ebba...@gmail.com 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.
