In the process of what to do about 40 meters at my new location and I have a few questions for the group.  I will have one 126 or 136 foot tower (Rohn 55 with Phillystran guys.  Plans are to stack tw

I believe Cushcraft coils have 68 turns of 12AWG wire. It is easy to get SWR bandwidth with lossy coils. The JK 2el Yagi should give you 2:1 SWRon the segment you require, I have a couple of OptiBeam

The Moxon JK 40m is another way to go. Proven stack performance with essentially the same design from modified CC 40m at K3LR. Really wideband. Cheaper too. An interlaced multi-band has to make some

I have JK Mid Tri 40 at 100'. I adjusted it at the 5 ft level for resonance as in the manual (200 KHz down), and the resonance turned too low at 7.020. SWR is about 2:1 at 7.1 and 3:1 on 7.2. But I a
