Hello
I like to experiment with aerials somewhat and was wondering about lowering the apex of my VEE from 70 feet to make it equal to the ends to come close to a flat-top dipole. The entire antenna would be 40 feet high total.
Something worth trying? Others are receiving me better on the vertical than the dipole.............hhhmmmmmm

Something's got to be seriously wrong if relative locals are receiving you better on the vertical.  What kind of feed; what tuner?  Also, 40 or 75 meters?

That height should work great on 75, but it might be too close to 1/2 wave height on 40, causing a null at high angles, thereby hurting relatively local coverage.

Sorry
I was on 160M and K1QAR heard me better on the vertical, Ted in Mass. I'm in Western Pa. Fran W3SCC Hagerstown was a problem even on the dipole. I think there was a WX front going through and it may have masked everyone's receive with a hissing sound and steady S-9, then it past. I think Fran was having antenna problems. KC8LII and another station near Fort Wayne heard me equally well from both antennas
I have heard of better results with lower antennas for 160M. Max range may only be a couple hundred miles.

Another late thought
I think it was the usual 3 or 4 S unit difference between the two antenna systems.
Ted said I was 40 over on the vertical and much lower on the dipole. No S reading available.
