I have a HAM friend local to me who uses a SteppIR 3 element yagi antenna, we quite often hook up on 20m to work Stateside, Penn, G0VQY puts out a fabulous signal, rare is his report anything less than 5/9, mine however is often 4/0 to 5/5 on my homebrew 40/20/15m dipole and 100 watts, but do I care, no not one bit, it just spurs me on to improve my station !
However on 10m with the Sporadic E running, my vertical 5/8 does start to give him a run for his money !
