Antennas on the East Tower
We now know the terminating resistors for the Vee Beam were two toaster elements at 137 ohms total resistance. Dave is endeavouring to source something better as the now-available toasters have much lower resistance elements and they are hardly non-inductive!
Checking the pivot bolts, which were badly rusted. L-R: Steve, Martyn and Harry.

Perhaps a squirt of this will help.
How about a little more leverage?
Jim and Harry cutting the rusted pivot bolts
We got one of the pivot bolts done. Harry and Jim in particular did a great job up the ladders and tower.
The next job is to replace the second pivot bolt and retrieve the rotator to see if it’s possible to repair. The two rotators we have ‘in stock’ are a different type and would not fit the current setup easily it seems.
