73 to ALL,

I am preparing to start the assembly of my "low budget" station and have a couple of question, please.


My first step will employ an azmuthal only inexpensive rotor (RCA VH22F) and a terrestrial use linear  dual band antenna (Jetstream JTBM270).  The antenna has 3 elements for 2m and 5 for 70cm.  I plan to offset the elevation of the antenna 20-30 degrees in a fixed position, rotatable of course.  My radio at this time is an IC-2730 dual band which can be used for the FM birds; I am told.


Having described my "phase one plans", my first question is regarding rotor control.  Does anyone know of a rotor control for a three wire inexpensive rotator?


Regarding the linear antenna, what would the best mounting angle be for polarization.  Yes, I realize that it would not be optimal mounted vertical or horizontal.  I assume that a compromise angle might help.


Let me explain that portable handheld operation is not feasible dues to my age and living circumstances. A fixed station is my only option.  However, that can be improved if necessary and financially feasible.


Thanks to each and all.

73,

Jerry  AB5R
