I've been gradually converting to all DINs everywhere that it's 
reasonable. Female DINs on main lines which are 1-5/8", and male DINs on 
the rotor loops and jumpers, which are Buryflex, LMR400, etc.

Male DINs for the braided coax are not cheap, but I recently purchased 
some direct from China at around $12 each, and there was no shipping 
charge. They are very good quality.
