[NLRS] 432 beacon

[Mary Brown]

Or maybe a stack of 4 six element cheap yagis(build 2 on one boom pointed away from each other to balance on the mast) http://www.fredspinner.com/W0FMS/CheapYagi/vjbcy.html aimed n, e, s, and w.4 element power divider for that frequency is small and easy to build.

Hi Art!

It would be nice to have another beacon on.  However, I think the 9wl is way too sharp.  Many people who would listen for it will be out of the path.  That antenna has a very sharp pattern - take a map and consider what you cover with 20 degrees;  beyond that your signal will be way down.  Yes, there may be a lot of aircraft in that pattern, but unless you want to do a study of aircraft scatter, the main purpose of a beacon is to indicate band openings.  For that, a much wider pattern is highly preferable. Sure there are not as many stations to the north and west, but people like VE4MA, K0AWU and NT0V will watch for your beacon religiously.

   I would suggest asking around for one or preferably two horizontally polarized omnidirectional antennas.  I think there is a good chance that you will find someone willing to donate an antenna or two.  A stacked pair will give you some gain.  These antennas are not hard to build, and you will likely see some being tested on the antenna range at Aurora '18.  Others here on the reflector can suggest which design is best to build.

We have 20 people registered so far for Aurora '18...  please register now at:  www.tinyurl.com/Aurora18
