Yes. You are practically sitting on top of the stations' transmitters. A coat hanger wire would be too large diameter. Something smaller gauge would be a better fit. If you have a piece of coax a foot or so long, remove all the shielding and outer insulation and just use the copper wire in the middle. Stick it in the coax port and run a channel scan for digital antenna channels. You may be pleasantly surprised at the results.
