This page covers the addition of a telescoping antenna to the Nady 151VR receiver. I used Radio Shack part # 270-4413A, a 24" telescoping antenna with a rotating base. I also cut the battery compartment off the Nady receiver so that the unit will fit into my flashlight housing . I operate the whole system from a pair of 1800ma 9.6 volt batteries from a remote controlled car, so I don't need the battery compartment anyway.

There is a row of inductor coils along one side (see the silver blocks with the little red circles. There is a skip in them right where the screw driver is sitting in the picture. That's where you want to drill the hole for the antenna

Mark and drill a hole just big enough for the antenna to fit through as close to the top end of the top cover as you can get it. You want it to fit tight and be as flush to the front cover as possible.

Once you get the hole drilled slip the antenna in and try the fit with the bottom case. Make sure there are no interference's with any of the electronics.

Next mark the location to drill a small hole through the top case so that you can run a screw through the front cover to attach the antenna You will have to put the screw in the hole and them place a jam nut on it and them the antenna before tightening down the nut. Other wise you wont be able to get it through the hole in the antenna

You will need to attach a wire to the antenna from the location on the board where the factory antenna is attached. Use the shortest possible wire you can manage and still get it hooked up. About 2 inches is what I used. Too long and you may degrade reception. Use a 50 ohm wire or just clip off the factory antenna and use that. I soldered a small eye to the end for attachment to the antenna Put another nut on the screw attaching the antenna and you are done.
