Hi Ken

Location, Location, Location and of course Take-Off Angle!

I had to lower a 55 foot antenna down to around 45 feet to hit our
local repeater only 3 miles away. At 55 feet it was blocked by a
microwave antenna, at 40 feet it is blocked by several steel framed
buildings. At 45 feet, there was a hole I could squeek through so to
speak.

Now, if I switched from a 5/8 wave to a 1/2 wave vertical, I had to go
all the way down to around 30+ feet to find this hole again.
