Philco doublet antenna installed - BDM - 03-18-2012

So, decided to stick up my Philco di-pole (doublet) antenna today. Results = fantastic! No doubt a nice improvement over my long-wire. This of course works in conjunction with the tuned antenna attachment points internal to the radio. Noise is lower. Good ground has little effect on the noise due to the tuned nature of the doublet (really the tuned input in the radio). Naturally the antenna itself is nothing more than a 60' di-pole. You could make your own. Simply cut up a 30'/30' di-pole and feed it with a twisted pair to the tuned antenna attachment points.

I later added another 20' to either end for a total of a 100' dipole. That improved things even further all across the bands. Those tuned inputs do work compared with the straight wire input (and ground).

For the BCB your will need about 500' per side to be resonant. At 100' your resonant at about 10Mc. I've got about 120' up in the air at 35' or so and it works well. The higher up the better, unfortunately I don't have any tall trees just 40' pines.
