I will have it permanent in-line with my RG 8 coax

I want dc power (no batteries)

accurate read-out

I intend on using it's readings to make length adjustments on my end-fed dipole antenna. Is anyone using Daiwa CN-501H2  HF/VHF ?

this is my first attempt to do this so any other advice or suggestions are appreciated

thanks !
