[HCARC] Field Day Antennas

[Harvey N. Vordenbaum]

Due to the limitations of the building feed through conduit we only have a
few coax's (RG-8's) available.
The HF antennas are combined outside by a remote coax switch box.  There is
one spare feed through cable however.
There are separate coax's for the 2M and 2M/.7M antennas.
Fred has an idea of replacing all the present RG-8's with RG-8X cable thus
gaining a few more lines passing through. Someone could make a calculation
about how many lines would be gained. Making this change would not be easy,
however and time is getting short.
For field day we may have to pass coax through the partially opened window,
but then you wouldn't want a generator running nearby.

Gary,

You may only need to put an antenna up for the GOTA station across the
street.  Questions you need to answer are:
         1.  Do the existing 40 and 80 m dipoles have separate transmission
lines?
         2. Can you operate one transceiver on the 20/15/10 Vertical and
another on the dipoles simultaneously?
         3. If the answer to 1 is yes, can you operate with one transceiver
on 80m and another on 40 m simultaneously?
         4. Is operation even permitted on 30/17/12 m for field day, if not
you don't need any WARC antennas?

If you can operate on 80 and/or 40 simultaneously with 20/15/10, then that
is probably all you need.  You won't be able to operate two stations on any
single band even with separate antennas behind the RC Building.  I suggest
that if you really don't need to add any more antennas you shouldn't.

You should check out all the antennas and transmission lines that are a
permanent part of the station a couple weeks ahead of time in case you need
to make any repairs.

If you are operating as 2 or 3F (why not 4F!!) then I don't think setup time
is even a factor since the station is ostensibly part of a "permanent"
emergency fascility.
