Bigger dimensions could give restriction, depending on your location and /or your neighbors. The antenna tuner system can match loads of up to 26:1 initial VSWR within a frequency range of 3. For this reason the 40 meter section was left a little long so that when the 80 meter section is the correct length, the 40 meter section resonates on the desired frequency. My question is will I be able to tune up to the 80 meter band with an atu and receive decent signals? Currently I'm using an end fed 40 meters long wire with 9:1 balum - its not straight but a big u shape. We will take an inverted V for 40 meters, an antenna which is widely known amoung HAM's as an allround antenna. Room in new location open to decent.
