New half wave end fed wire tuner for FT817nd

P130410_22.26_[01] (Medium)

Here is a photo of my new half wave end fed wire tuner, i made it for use with my FT817nd, it will fit direct onto the SO239 socket on the rear of the rig. It will tune a half wave end fed wire on 40,30,20,17,15 and 12 meters. It has a built in LED SWR bridge, using a super bright led, which can be seen easily even in direct sunlight, a must for portable operating. The 4K7 resistor you see across the terminals was used to test the tuning range, 4k7 being an approx of a half wave end fed.
