I will probably do some more playing around but here are my measurements if anyone cares. Shown are EFHW-8010-2W Antenna tune measurements: Band / (AS IS antenna length 130ft) SWR, and SWR after antenna shortened 2ft. Sorry I don't know if it is possible to embed a file so here is the raw plain readings I took. The 'red' numbers are well above 3. You can see I sort wiped out my 10m bands trying to tune for 80m.
Tuning the antenna before the license? Naughty, naughty! de N4HHE
OK with something ultra low power such as a nanoVNA but not with a transceiver and tuner.
Fixation on SWR is soooo CB. You would like the antenna to be resonant in transmitting frequencies but the big concern is reflected power. Not the ratio of forward to reflected.
