I am getting ready to install a second LM-470 and I have to run
hardline, 115 VAC, rotor cable and Ameritron remote switch cable from
the shack to the tower. My guess is the total run will be around 500
feet. Since I know a lot of you have already installed runs of this
length, I have the following questions:
1. Do I have to worry about voltage drop for the 115 VAC on a run of
that length? The AC is needed for raising and lowering tower.
2. Do I have to worry about voltage drop for the rotor voltage?
Should I be using heavy gauge rotor cable?
3. I will only need two positions on the Ameritron switch. Can I get
10 conductor cable suitable for both the rotor (8) and the switch (2)?
4. There has been a lot of discussion of running cables in conduit
over the years. What is the consensus opinion on the best way to
do this? My recollection is that some provision has to be made to
allow for the evaporation of condensation. Is it permissible to
run all the cables above in a single conduit?
I know there has been discussion of some of these topics before but
searching the archives is a pretty tedious task. If someone can provide
the information in a nutshell, I'd be most appreciative.
73, Joe
