[MRCA] MRCA Meet Communications Readiness Bulletin II

[Gene Smar]

Gents:

     I can bring along my AS-2259-like NVIS antenna for the remote site.  Also, I have enough fiberglass poles to make a second end support for a simple dipole out of it if needed.  

     Let me know.

The dipole that we always set up at base is a perfectly good NVIS antenna.
