Hi everybody !
I work Oscar13 with two Yagis mounted on an horizontal 6 ft metallic tube :
\ / []
\ / -[]- \ /
\=============| [] |============/ rear view
/ \ -[]-elevation / \
/ \ [] rotator
10 elt XY vertical mast 12 elt XY
144 Mhz to azimuth rotator 432 MHz
RHCP RHCP
The questions :
1. what should be the smallest distance between the two Yagis ? (i'd like to shorten
the tube)
2. Is a non-metallic tube absolutely necessary ?

To: ham-ant@ucsd.edu
I have just acquired an AEA 10 to 30 Mhz Loop Antenna. Before I get
it in the air, I would like to hear about any experiences that you may
have had with this antenna. I have read the reviews of the 10 to 30
Mhz and the 14 to 30 Mhz versions in the ARRL Radio Buyers Sourcebook,
Vol 2 (Great book, by the way!) but would like to hear about other
real world experiences..
