I have Hustler 4BTV Vert that is tuned below 1.5:1 SWR w/o tuner. When using internal SWR meters for either Yaesu 450d or Yaesu 890AT niether will "tune" and just keep rattling unable to tune. Why will they not tune the antenna when w/o tuner Im already below 1.5:1??? Is this a problem??
Well, if you tried 2 different radios and they are not tuning the antenna, you have your answer. You have a problem with the antenna or the coax.
1. Did you tried tuning each radio with a dummy load.
2. When was the last time you measured an SWR of less than 1.5?
3. Was the SWR less than 1.5 for each of the 4 bands?
Being that there are 2 radios no tuning with similar symptoms, the problem is likely not in the antenna.
