I dug this out:

I have just completed another test of mobile antennas. Last time I
posted the results of the 7' Firestik compared to the 108" whip.
The Firestik won by a small margin. This time six antennas were
tested. They were kept anonymous to the signal readers until
after the figures were compiled. Each antenna was assigned a
letter. Here's the list:

108" stainless steel whip A
8' Francis Amazer B
7' Firestik C
6'6" Hustler top load D
5'4" X-Terminator double coil E
9' homemade 1" braid antenna F

A picture of these antennas and the mount
is located in (alt.binaries.pictures).
The file is called (antennas.jpg)
* The braided antenna is not shown.
It was included in the test after the picture
was taken.

The conditions of this test follow:

1. All connected to Hustler Quick disconnects
2. All used at 1.5 : 1 match or better
3. All tested with a constant tone, constant power transmitter
4. All used on a three magnet mount on the roof of a truck
5. All tested from a parked vehicle that never moved during the test
6. All tested within a very brief time period of each other (15 sec.)
7. All used two stationary receivers 14 miles away.

The analog S meter of a Kenwood and Tentec were used to
compile these numbers. These numbers were averaged after
numerous checks and rechecks to make sure the order of
best to worst was accurate. Here they a

Tentec: F, 3.1 s units
E, 3.05
A, 3
B, 2.85
D, 2.7
C, 2.65

Kenwood: F, 2.3 s units
E&B tied at 2.2
D-C tied at 2.15
A, 2.1

Two things come to mind.
1. All these antennas are close.
2. Antenna E, easily the shortest, outperformed
or equaled everything except antenna * F

* ( antenna F is an impractical antenna. It consist of
a one inch wire braid covering a fiberglass rod 9'
tall)

Comments welcome.

Wow!!!! Yup brings back memories of the good ole days of discussions
here about things like antennas, swr, even mobile beams....
