Hi All



I finally got the vertical up and running, problem I have now is I can't find a 
low SWR on the coil, the best I can get is about 2.8:1 no matter where I tap 
the coil that's the best SWR, I can move that point up and down the band by 
moving the tap but the SWR stays the same,

My current set up is about 55ft vertical I have 2 loading wires in a T shape, 
wires are 50ft either side of the vertical and the are pretty level and in line,

I have 38 radials averaging about 45-60ft long, I will add more when time 
allows but don't the make the SWR worse ??

With no coil I get resonance at 2.12mhz with R=16 X=2 on my MFJ269,

The coil is 25ft of 5mm copper brake pipe in a 4" diameter, the coil is 
attached to base of the vertical and the other end is grounded,

Any pointers on what I can do to get a better match,

Thanks
