Copper pipe

[Tim]

I made a mobile antenna years ago using 1/2" black plastic conduit about 3ft in length, wound 11 metres of 17A automotive cable around it, tight wound at the bottom gradually getting wider to the top leaving a 'tail' at the top to trim for SWR tuning, the bottom end I cut the head off a bolt, same thread as a mount on a 7" magmount, drilled a hole through it and the conduit, put a bolt through to hold it al together, wound black PVC tape around the conduit and wire to hold it all in place, looked really good on the roof of my mini and worked a treat! I called it a 'thick stick'. Still have it in the shed somewhere.
