TV antenna
antenna jack: A coax connector was added to this weather radio. Now an external antenna can be connected to improve reception. The connector is mounted on the side of the radio near the base of the telescoping antenna. Got the F connector by taking apart a tv signal splitter. The mounting bracket is cut from a piece of aluminum angle. Holes were drilled for the F connector, two small bolts and the wire that used to go to the rod antenna. I plan to run coax to a homemade 3 element yagi antenna that will be in my attic. For now, I can connect up to the coax coming from an outdoor tv antenna.
