A few weeks ago I posted a message asking for information on ntp software. I would like to thank Bob Cunningham, Erik Fair, David Schachter, Milo Medin, and David Curry for all of their advice and assistance. Now that our PSTI Time Source Clock is up and running, I have another question. Can anyone recommend a good outdoor antenna? In fact, it does not have to be good. Kauai is not that far away, so the antenna could be mediocre. I am looking for something that is a little better than the indoor antenna that was provided with our PSTI clock. (I did not order the clock, therefore I did not select the indoor antenna.) The clock.txt document contained information on available clocks. Is there a document with antenna information? If I receive enough responses, would anyone be interested in a summary? I would like to stay away from the copper wire antenna kits. I do not think that the university would approve of the placement of copper wire between the two coconut trees in front of our building. (Besides, I possess very poor tree climbing skills. :-) A nice roof-top whip would be great. Thanks - Kevin -- Kevin Y.

We ordered the outdoor dipole antenna ($295, includes 100' RG58, BNC/UHF connectors, tripod mount) from Traconex and it works great. They also have an outdoor whip antenna ($95, includes base mount and UHF connector, whip is 96"). Prices are from an '88 price list. Be sure to get a grounding block and/or lightning arrestor kit so your clock and everything else doesn't get fried. Jim Knutson knutson@mcc.com cs.utexas.edu!milano!knutson

Jim, (kaff) $295? May I suggest you scare up a ham radio op for advice? We are talking a hunk of enamel wire, a couple of insulators and a hank of RG58. I make it about $20 worth, including the fishing line use to hold it up. The important thing is to get it outside, away from steel building frame and power wiring as much as possible. I have easily a dozen communication receivers here and on campus with antennae from a casual hank of wire to 30-foot aluminum monstrosities. My conclusion with the Traconex clock, of which I have two, is that a few feet of wire in the clear is sufficient, although the one I have on dcn6 is hooked to a 135-foot dipole shared with several other receivers. That one of course works gangbusters. Dave
