If i take the center conductor of a coax hooked to any antenna <mobile/base>(any coax).
and connect it to a 200ohm resistor input.( i know resistors do not have input output sides to them)
Then add a 100 turn pot wiper to the same input of the resistor.
Then take the output side of that resistor and the pot low side of a pot
back to the scanner.
And using the pot for a antenna trimmer what do i or should i get?
The coax can be anything and any ohm and the 100 turn pot can
be any ohm as well.
The question is.................. what is the resulting factor of using a resistor inline
with a pot to make adjustments to a antenna.
The variation in the ohm rating of the pot and the resistor will of course
have an affect on the adjust.
Your input is welcome.
I have already tried this, and i am looking forward to your comments BEFORE posting the outcome of what i have tried.
and maybe i need to change some things for better adjustments and better results.
