The SR-5 - A 9 element multi-Band HF 5 Band Super-compact Yagi covering 20m/17m/15m/12m/10m bands with a single feed point

The SR-5 has been reduced by more than 30% in length while giving the same performance, 5 HF bands consisting of 20/17/15/12/10. The SR-5, comes with a capacity loaded 20m element Option and reduced turning radius too!

The boom is made from 45mm diameter square tube with a wall thickness of 3.2mm and thus is super rigid. The largest diameter elements are the 20m
