The boxes were chosen to fit the resistor assembly
and transformer. Figure 14 shows termination resistor in open
plastic food box. Figure 15 shows transformer in open plastic food
box. Each box was closed by cover.
Then several turns of a vinyl plastic tape (I used
electrical tape for outdoor application that should work at temperature
range: – 20 C to + 60 C) were coiled above the cover. Figure 16 shows termination resistor
in closed plastic food box. Figure 17 shows transformer in closed plastic
food box. Coaxial cable is going to basement through a window
with plastic insert. The insert made from soft foam. Figure 18
shows the plastic insert on the window. Near entry of the cable
to the plastic insert the coaxial cable was coiled in a small
coil. The coil was an RF Choke that closed way for stray RF currents
inducted to outer jacket of the coaxial cable to the transceiver.
Also the choke gave additional protection from lightning. Figure 19 shows the RF choke.
