Hello Arnold.If you happen to have used a Channel Master line amp. There is a switch inside the upper box. I think it is buy default in the dual head position ? If you missed this and did not set it single head input it will not work properly.
I'm thrilled to confirm how well my project antenna is working! The tower is standing. The head is now 35' off the ground and working very well. As everything is out 60 miles, I installed a Channel Master 15db pre-amp and I have 22 channels clear as a bell. Great project
Update:Poor performance above channel 42 prompted me to re read the instructions. I then re measured my tubes.Each tube was 50" a full 8" longer than the plans called for. Then add 2" for the 90 deg elbow and the spacer on each end. After careful measurements where taken.I removed the 90 deg elbows, spacers and caps from both ends of each tube. Cut the pipes 39" then re attached the 90 deg elbows mounting spacers and end caps. Adjusted the 3/4 PVC arm lengths. Re bent the tubes to fit and re mounted the tubes. Boom! The picture cleaned right up on 29 & 42, 51 is now not only there but flawless! Transmitter towers are close. After that everything is 45 and 60 miles.Hoping to get them.Tower is laid out in the back yard. will be mounting the antenna and standing the tower in the next few days. Will post pictures and results. Ron
