Update, all is good, Rabbit 73, your plan worked with the Radio Shack Diplexer and the splitter. With a bit of movement of the Antenna, I am getting a 78% signal.

Thank you for the good news; you made my day.

The problem with my Samsung was that I had a bad connection with my coaxial cable which was ok transmitting the UHF signal but wouldn't transmit the VHF signal.

I have seen that happen with cable signals. The low cable channels were very weak, but the high channels were OK. The coax shield was not making good contact at the connector. The low frequency signals could not jump the gap, but the high frequency signals could, because there was enough capacitance at the gap to pass them with little loss.

My only remaining issue but a very small deal is that I am getting WHYY PBS on the Olevia with a 68% signal, but not getting anything on the Samsung.

If you want 12 a little better, you can make a folded dipole for 12 and combine it with the folded dipole for 6 using a HLSJ. Then use a UVSJ to combine them with the UHF signals.

Channel 12, 204 to 210 MHz, center frequency 207 MHz.
5540/207 = 26.8 inches
