Although linearity is inherent of the specific device and different amplifiers behave differently, the admissible output level of an amplifier to keep constatnt its charachteristics of linearity is a

This is not surprising, but you have low loss elements. A 3/4 dB means that the overall efficiency of the antenna 1 in respect of the antenna 2 is between 40 and 50%. Considering that your element lo

about key clicks and having to perform post-production mods, far less feedback than that for us to say "hey, maybe we As a product manager (not in Ham radio) I suspect 50 letters about key clicks co

Two verticals at very short spacings can't develop any other than a cardioid pattern, the F/B is (may be) a sharp notch and the F/S is a mith. If your EWE can be long enough to have the verticals at

I got a private e-mail by Doug NX4D who pointed out the pattern of his antenna, a rotable end fire array of two resistively terminated non resonant loops. It occurred to me that I found a similar con

. zero Hi John, first of all thanks for the reply. The intriguing points for me of the antenna in question, if compared to a classical low loss (top hat loaded) short monopole is the SWR flatness joi
