HF Yagi Refurbishment
The clubs HF Yagi (a Cushcraft A-3S antenna) is in need of some refurbishment to put it back into a usable state. Some parts of the antenna have either corroded away or have been lost and need replacing, while others can be restored to working order.
Antenna Details
The HF Yagi is believed to be a Cushcraft A-3S.
This is a 20m, 15m ,10m yagi.
It was acquired as it was being thrown out by a Scout Club near Basingstoke, prior to the departure of their only licensed staff member.
