Has anyone tried building or considered building a J-Pole antenna for their scanner? With Woodstock PD going encrypted most of my listening has dropped. I can pick-up Aylmer/St. Thomas police but quite often the signal is weak. I'm hoping to improve signal strength. I have researched on the net & have plans which I will try in the next few days. At worst it will be a learning opportunity. I plan to set up the antenna centered for about 142.5 mhz. Also the plans say there may be an increased signal in the 400mhz range which would be great. Without a transmit option I will go by the plans for tuning with leaving the option for adjusting the feed point for better reception. Hoping for the best.
