ok guys i have a few questions i cant find answers too, 1. when using my antenna analyzer to tune my mobile antenna, should i use a really short piece of coax to tune the antenna or should i tune the antenna through the full length of coax i operate with? 2. should i make my operating coax a resonant half wave at op frequency using the analyzer? 3. should i tune the antenna out in the open like a field etc. away from houses, trees, poles etc for an accurate result? or does it not matter?
