I had a driven element on my 3 ele 20-6 mtr Steppir that I never resolved but 
it would lose RX signal strength. Bypassed coax, checked for fractured solder 
connections in the EHU (think that is what they call it) and finally got 
Steppir to send me another used unit for a pretty good price. Still got the 
unit and have considered trying to turn my 3 el into a 4 element. But that 
would require some expensive work and removing the steppir way up there at 
118'...so it's just not worth the cost and trouble. If I ever go that far I 
will probably put up something like a DB36 or DB42 or maybe a JK antenna. Or a 
big Quad array. But so far the 3 element has given me very good service and as 
the sunspot cycle improves it should show it's stuff. My favorite band has to 
be 12 meters although I pretty much try to work them all on SSB. 
 But I never was able to resolve exactly why I was losing half or more of my 
signal on receive. As soon as I hit the TX key, even on SSB, the signal would 
come back up. Like tickler current on old phones I thought.
