Rob,

You are missing the point.
You say nonsense but the information you provided agrees with what Jim stated. hihi

Jim said: "verticals have little or no high angle radiation, but that only matters if you're
trying to ragchew within a few hundred miles"

You said:  "the vertical is worthless within a few hundred miles"



A vertical can be used for both local or DX with the limitation of a few hundred miles for local as Jim stated. I have used a vertical for years on 75 and ragchewed up and down California and Nevada quite well and worked beautifully on DX also. The objective of DX or local dictating my antenna choice is an urban myth as Jim stated. With the exception of close in ragchewing the vertical met both objectives of DX and local. Actually I found that with close in ragchews on 75, yes the signal was reduced but it really didn't make any difference because they were usually around S7 to S8 anyway. I'm sure with a
horizontal wire antenna they would have been well above S9.

That's an urban myth. Yes, verticals have little or no high angle radiation, but 
that only matters if you're trying to ragchew within a few hundred miles. See the 
links I posted for >some real science on the topic.

Nonsense.  It's not an "urban myth" at all.  I have a friend on 75 m.
who's only antenna is a vertical, base fed over a ground system, and
he's around 60 miles away from me and is usually at the noise level.
I have a dipole, horizontal, fed in the center with ladder line on 75
m., and it is 45 feet high.  I have a 65 foot high quarter wave
vertical on 75, base fed over a ground system of 101 radials as well.
The vertical is worthless within a couple hundred miles and is equal
with the dipole at around 500 miles.  At 2000 miles out the vertical
is 20 dB better than the cloud burning dipole.   The height restricted
ham should consider his objective.  If he only wants to operate on 80
m. casually, with his pals inside 200 or 300 miles, a horizontal wire
antenna is absolutely the way to go.
