Thanks for all the discussion.
I do appreciate the suggestions of the different
cost-efficient antenna possibilities being fed by 1/2" coaxial cable
variants. They are the real-world info I was looking for.
I think I will just go with a basic Kreckman,
Diamond or Comet (in that order) and some RG-214.
It is looking like the Site will require less than
20 feet of Coax from Duplexer to Antenna, and it will not be a tower, but inside
the Elevator Access Building at the top of the local
Hospital.
The antenna will be mounted to a fixture
firmly attached to the top and wall, and it will share the grounding
system already in installed for other antennas in place. I
hope to do a visual inspection of the site in the coming week, and hope that
there is no inter-reaction of elevator cables (if that is the transport type
used) and the antenna's RF field. So far, the antennas in place are for a
digital node that outputs 65 Watts on 2m and has not created problems.
Unity Gain and a light wind resistance Omni should
do what we need it to do.
The Hospital is close to a Hercules Powder plant
that makes a number of products and produces a hostile environment for anything
metal in the area. The location is also line of site to the Inter-Coastal
Waterway and the Atlantic Ocean. End result is antennas will be budgeted
for replacement on a basis determined by usable lifespan of original.
If some of the suggestions I received were
based on the experience of others, there must be a great access to Crane
Operators and Equipment to host large payloads to great heights, being fed by
Coax that is nearly the diameter of the average tower leg. (tongue in
cheek)
I have around 100 feet of new 1 5/8 Andrews
hardline left over from a Cellsite installation, but don't care to float the
loan for connectors and then have to pay for extra guy wire on the opposite of
the tower to bring it back into plum. :)
Thanks Again for the suggestions,
David
