Dear Readers, I have a similar setup to that of SP5EWY, but minus the extra 30mx piece of wire. The tower is 16mx high with a A3WS and a 204BA on top (plus a 146mhz collinear vertical). I run three 1

Hi, will apreciate if someone have experience and comparisons of shunt feed tower and slopers. I will rise a 118 feets tower and my first idea was to shunt feed it, but seems that will work bad if I

The antenna you describe is 1/4 sloper. The tower radiates and the effectiveness is very dependent on the tower, guy cables, mast and beam on tip. You have to model your installation to see if it a g

IMHO a wire 1/4 wave length long wire should preferably be electrically connected to the tower and fed from the bottom of the slope against a good ground system. AM stations that have done this in em

I called it a half sloper because that is what you did. It was obvious from your post what antenna you were talking about, so no confusion there, but to be correct, I should say this about the names.
