Just build the KM4ACK EFHW today and threw it up in a tree, about 35 feet, sloping to ground. Put an SWR meter on it and found the lowest SWR I can get is 2.3 and that is at 6.8. I tried shortening the antenna by about two feet, wrapping the excess around the antenna. Almost no change in the SWR, still about 2.3 and that is at 6.9, Before I tear out the transformer and rewind it, could anyone suggest troubleshooting tips? Continuity checked out.
Thanks,
Phil, K3UT
