Our Mobile Ham Station


Converting a 12' Utility Trailer into a Mobile Ham Shack

Around the middle of 2017 the officers and other interested members began kicking around the idea of having a mobile station that we could use at Field Day, take to the monthly outings, take to social events, activations, etc.

We presented the idea and some rough cost information to the members in january 2018 and received approval to purchase a used trailer and start work.

To that end we:
- Incorporated as Davie/Cooper City Amateur Radio Club so that the club could own the trailer, not any specific member
- Purchased a 1,600 lb, 12' long utility trailer, transferred the registration to Davie/Cooper City Amateur Radio Club
- Had a license plate issued for the trailer (will apply for a ham radio tag with the club call sign) (Rich WB4EHG)
- Determined what mods needed to be made to the trailer and created rough drawings (Pete, N8PR)
- Fred WB4BAG is having the mods made by his company free of charge!
- Started a Trailer donation fund (Tom, N4MEO)
- Started receiving equipment donations from members

Trailer specs: V nose, 6' by 12', ramp door, recessed track in floor

Trailer in progress 2:
-- Steel outboard frame rails added to
    make a new, longer tongue.
-- Old rails were 2" x 4" x 1/8" wall. 
    New rails are 2" x 2" x 1/4" wall.
    (1/3 heavier).
-- New 2" ball socket welded to the
    extended tongue. 
    Old tongue rails remain in place
    as added support.
-- Will now begin fabrication of the
    "tower hinge support".
-- Would not have been easy as it is
    without Pete's drawings!!!!
Trailer in progress 3:
-- Not in view are the reinforcing
    rails under the new tongue plate.
-- Room was left on the new rails to
    mount the spare tire carrier and
    the new tongue jack (has a wheel
    instead of a foot).
-- Tongue plate serves as a base to
    mount the tower support structure.
-- The 1/4" tongue plate added critical
    strength to the tongue and only
    delayed initiating fabrication of the
    "tower hinge support" by one day.
-- Planning to have a mounted tower
    by Friday, May 18.
Trailer in progress 4:
-- The mast is in place over the trailer body
-- The antenna it attached to right side of
    the mast
-- The left side then pivots down causing
    the antenna to go up in the air.
-- The mast is then cranked up to the
    desired height.
June 5, 2018, Fred brought the trailer to out June club meetiing. This is the first time we have seen the trailer with the new tongue and tower mount & raising assembly. The photos below are what we got to see.

September 16, 2018, The first outing with the trailer at Vista View park. We setup early in the AM and operated some FT-8. We learned some lessons that will be applied to future outings.

Neil WB2RUU has done a fantastic job on getting the trailer operational!
