Look for TV antenna rotator: used to be common from USA/Japan

I can't find a low cost rotator either. A recent RadCom has a DIY project. And I saw somewhere one made from a wiper motor.

Hello Patrick,

I’m hoping you are in the UK as I’m looking for an inexpensive rotator and I was wondering which model you bought and from where.

There used to be loads of them in the UK but they all seem to have disappeared. Even the cheapest Yaesu is both very expensive and overkill for a simple loop.

Got it.  Yes, the current setup is bicycle wheel.  Will try a smaller gap.  Also I purchased a rotator so I can play with the direction as it gets colder, without stepping outside.


Once I am happy with its ground performance will try a higher mount.


By the way, using 75ohm coax connection, I assume that's reasonable.

If you are using a bicycle wheel rim the spacing doesn't need to be very much. On the one shown in the video the gap is only the width of the saw cut. I made a fibre glass spacer to keep the wheel rim in it's original shape.

I'm planning to make another video this week showing how to make a loop out of a bicycle wheel rim. That should explain it better than a text description.

Regarding your strong local station try nulling it out with the loop. You should be able to get a very sharp null up to 40 dB down.
