43 ft Vertical

[David Little-6]

The other half of this vertical antenna is the ground system. Without  
that other half, you will be wasting your time and money on the first  
half. The proof of this - you would never dream of putting up half of  
a dipole. Hi Hi

Sure.  It's called an End Fed Half Wave dipole.  Oh, but to some, that's not an antenna.

The other half of the antenna is the braid of your coax unless you use an unun and connect the antenna to something like the ship superstructure or the sail of a submarine.  I used a 114 ft wire connected to the sail of a sub this weekend and it worked pretty well, but not nearly as well as my SteppIR.

It is an antenna and a good one, but it is not half of a dipole, it is  
a whole dipole.  It does not matter where a dipole is fed, it is still  
a half wave long.

Perhaps that is true about a Monopole Vertical which by the way CAN
have a ground system consisting of a ground rod, which is very
inefficient, unless standing in salt water.

The Half Sloper is an efficient wire antenna which uses a tower or
other grounded metal pole as it's other half, but in that
configuration the wire does not radiate a great deal.  The pole or
tower does the radiating.

See "The ARRL Antenna Book" or "ON4UN's Low-Band DXing".

What you are describing is a half wave end fed wire which has the
other side of the circuit attached to ground.  

For an antenna to be a dipole it must be two individual wires each fed
independently by a balanced or unbalanced feed line.  Each of the two
wires may be as of different length.

Well if you double the frequency, then add a quarter wavelength of
ladder line, you have the original Zepp antenna, or the modern
equivalent, a J-pole.

"It is an antenna and a good one, but it is not half of a dipole, it is

I beg to differ.  A dipole is an antenna with two elements fed at the same location.  A half wave end fed is only one element that is a half wave long.

I find this discussion pretty enlightening as I too plan to use my 50 ft.
fiberglass mast to support a vertical as well as my G5RV. (Well, not really
a G5RV as the ladder line will run all the way to the shack.)

Sadly, I feel the dreaded "End of Thread" message coming though. As always,
take care es...
