The G3XOV Version of the JOYSTICK Antenna!
by Ron, G3XOV

Resurrecting old memories

I used a Joystick from Partridge Electronics in the late 60's and was very impressed with the results. I also had the matching tuner from the company known as the Joymatch. It was a Pi configuration built into a small plastic box. Several of these tuners were available ranging from a receive only model up to the "4RF" which was the one that I used and was fitted with a small meter on the front panel that had a simple pick up wire lying inside the coil of the Pi network. You just tuned for maximum deflection on the meter!

I had very good results on 160 metres, working all over the UK and near Europe using our then, maximum of 10 watts on that band.

I still use a variation of that antenna in the shape of a 20ft vertical with the coil 12ft up from the bottom and fed through an SGC Autotuner. I can usually work any DX that I hear from 40 upwards with just the 100 watts of CW.

Good to resurrect old memories. You can experiment with it using my plans below.
DRAWING OF ANTENNA:


Drawing of JoyStick showing lengths, coil and wooden dowel.
Coil is connected on each end to aluminum tubing.

You will need a good random wire tuner to go with it. Mine was used AT the base of the antenna.

I use one earth rod close to the tuner only about 2 ft long and just one radial bent across the top of garden about 30ft long and just lying on the ground at the base of the fence. The overall length of the aerial is 20ft and the tubing is 1 1/4" diameter aluminum. The coil is wound with spacing between turns of about 1/2" and works very well from 40 up. Just fill up the wooded dowel with enough turns end to end and connect each end to aluminim tubing.

The wooden dowel acts as a coil form and support for the coil assembly.

Tape and seal the coil well after completion.

It will tune 1:1 on all bands 160 to 10 with the remote tuner but, of course it would need more inductance to be usable on 160/80.

The whole thing is attached to a corner of a metal framed greenhouse (with insulators HI) and needs no guying. It's been up for about 20 years and I've no plans for changes.
It works, so I leave well enough alone! 73, Ron G3XOV
