Hi Group,
I picked up a nice AEA AT-300 tuner. It's a bit different than anything I used before from MFJ. MFJ has the one lnductor with two tuning caps where as the AT-300 has two inductors and one tune cap. I connected me off-center dipole, which has 80 feet on one leg and 40 on the other and is fed with a 4:1 balun at the input and 50 feet of RG-58 down to the tuner. I also have a MFJ-269 antenna analizer and would tune the AT-300 using the reading for the impedance and shooting for 50 ohms with no reactance as indicated by the MFJ readout. Well, now, it was very hard to tune and I found that it was more like trial and error. So, is there a method of set up to maybe select one inductor for best 50 ohm resistive and then select the other for best minimum reactance and then tune out the VSWR with the capacitor?
