[amsat-bb] Quadrifilar home brew

[Dave Guimont <dguimon1@xxxxxxxxxx>]

Apparently some people are having success after constructing the 
quadrifilar antenna described at:

http://home.san.rr.com/doguimont/uploads

The antenna construction file is Quadfil1.zip and describes measurements 
for 2M, 435 and wx antennas.  Very inexpensive (the N connector costs more 
than the rest of the antenna) and easy to build, but measure the lengths 
carefully, particularly at 435, and obviously a short and low loss feed line...

The users keep asking me for gain figures, and I have absolutely none...
Coverage is nearly hemispherical, and estimating 2-3 db at boresite...with 
an estimated beamwidth of 150ƒ...

I have a narrative for some comparisons at ANTEVAL.TXT.

Be very happy to answer questions.  I've not tried it on AO-51, but it 
should work very well reading reports on HT users...I'm very interested in 
your successes or failures...

It worked, but producing a very weak signal, when AO40 was at minimum 
squint angles...Another reason for me being anxious to do the testing on 
P3E..!!!

                    Disagree: I learn....

               Pulling for P3E...
