Is there a manufacturer of metal (no wire) 20 meter folded dipole antennas? This would possibly enable me to use it on my motor home & store it on the roof without dismantling. 73, Julius KF5BBB

Hi,

I suspect you will have to fabricate one yourself. Do you really need a folded dipole just for 20m? As I suspect an aluminium tube folded dipole with a length of 30 feet plus with spacers to keep the two legs at the same distance apart and its mounts will be quite heavy.

DX Engineering have some parts you may need to fabricate one. They also do a rotary 20/15/10 mtrs dipole. See

All the best

Another possibility may be to use a trap dipole--traps reduce the length, Mosley makes triband trap dipoles that are just 17 and 24 long. As a bonus, you get 10 and 15 meters! (TA31jr and Mini-31-A)
