Default Need Ideas for HF Antenna at Fire Station

Dear Bob:

It is nice to hear from another of W8JK's boys.

You have received some good ideas and discussion.

Having dealt with the underlining need you described, the technical
issues usually turn out to be minor as compared to the people issues. What
you are likely most to need is a sharp people-person who can uncover what
the real reasons are for the apparent need for invisibility. Once you know
what the actual issue is, you can work to optimize the system.

You must have the clout, once you understand the people issues, to
convince the right people about an effective antenna system.

My preference is a dipole with about 100 feet of wire on each side that
is supported in the middle by a 40 foot tower. From the feed point to the
base of the tower I would run a piece of solid-outer coax that is heavily
choked with surrounding choking-material. At the base, I would attach a
commercial auto-tuner and run its coax and control cables (well choked)
underground to the station. An embellishment would be a second dipole at
right angles (connected to the first dipole) that is resonant around 5.4
MHz. A good fence around the tower is desirable.

Feel free to contact me.
