13: The "yagis" are Gold Medal Products TV antennas.
Products #8705 rooftop TV antennas. Each photoetched
metal kit provides us with three styles of large antennas
that can be easily modified into smaller railroad band VHF
antennas by simply trimming the thin metal, then mounting
the antennas to the lattice frame of the tower.
With the centerpiece of our base installation complete, we
can focus on the ground level. With the electronics con-
cealed in an equipment enclosure adjacent to the tower, all
we need to model is the enclosure itself. A large electrical
box manufactured by BLMA (#4312) has both the correct
size and look for this type of modern installation.
While the enclosure generally follows the standards estab-
lished by a particular road, one difference of a radio base
enclosure is the addition of air conditioning. Radio equip-
ment is temperature sensitive and it is common for a base
enclosure to have a small window style air conditioner fit-
ted, relieving the sensitive electronics from heat build up.
