For some time I have wanted a more accurate antenna elevation measurement system. Shaft encoders are beyond my budget. It seems sensible to use a pendulum operated system. Digging through my 'junk' box I find I have a new Spectrol precision potentiometer still sealed in it's package. This pot is 21mm diameter, has a servo type mount,, ball race bearing, 340 degree track (continuous rotation possible) and specification is 0.5% linearity.and is very low torque. Does anyone know if there are any drawbacks to using this method of position measurement. 73 de Dick G4BBH
