Well, let me just post this at the bottom. RCA made a line of VHF TV transmitting antennas which were a slot arrays.
The only one I managed to get close to before it became airborne and clamped a thousand or more feet in the air was for
channel 9. It was 80 feet long (2 - forty foot sections) and was constructed exactly as Tom, K7ITM suggested, the phase
of the feed of each element was progressively changed, in this case, to effect 1.5° of downtilt. I would suggest
contacting RCA TV antenna engineering for their design parameters, but they seem to have gone somewhere.

Is there anyway to down tilt the signal on horizontally polarized omni slot
antenna? I would like to add 1-3 degrees of downtilt.
