[Antennas] Vertical antenna

[Deon Erwin]

Hi Chris

The manual does not give the tophat dimensions and I measured it from the
tip of the spoke to the center of the hole as 255 mm.

I replaced my tophat with a large stainless steel washer with three
stainless steel spokes welded to it at 120 degrees separation.  I used thin
spokes to not add additional weight to the original design and used the 255
mm dimensions, from the tip of the spoke to the center of the washer hole.

| To all those who suggested that the antenna that I had given to me was a
| HyGain 14AVQ/WB were right on.
| The orginal owner found the book.  However, he lost the top cap.  The
| documentation does not appear to have the dimention of the three spokes
| forming the top hat.  They look like a piece of wire with a loop to put
| over the top, one above each other, and space each out 120 degrees.  I
have
| some Al wire that I can bend but was wondering what length?
