Hello All,
I am building a DL6WU Yagi for 2 metres and am wondering if 1/4 inch
stainless steel tube would be okay for the directors and reflector. I
have been given some so it would save me from having to buy aluminium.
I will still use aluminium for the folded dipole and for the boom. Any
thoughts would be welcome.
Cheers
Max


It will probably be a bit lossier than using Al but my first Yagi on 288
MHz(in the early 60s)was made out of 8g fencing wire and it seemed to work
reasonably well. Try the evaluation version of Eznec - I think you can
specify the material.

MMANA gives 3dB degradation for Fe over Al (11ele DK7ZB on 2m), which
surprises me. What does Eznec give ?
