The following scans are for a Hustler mobile antenna set with 10, 12, 15,
20, 40, and 80 meter resonators. I have a 3 resonator adapter but
didn't give that a try yet. Each of the antennas were set up to the
center of the band except the 80 meter which was set up for the middle of
the phone band (should have purchased the 75 meter coil). Measurements were taken
from the inside of the trailer.This antenna has been in use since 1996 with good
results.
Antenna:
Hustler 10 thru 40 are the 400 watt with the 80 a 1000 watt, 52" mast,
SS
quick connect
Feed: 12 ft
RG/8x
Will try a short section of RG/8u for better results.
Most of the scans have two graphs, one that covers a wide range and one
for band specific for the resonator. Most required just a bit of
adjusting except the 80 meter resonator - that required reducing the rod
length by 3 inches because it was designed for 80 meters, not 75 meters.

10 meter (1st scan 25 - 35 MHz, 2nd scan band specific) The jagged
scan on the left turned out to be caused by the trailer moving causing the
quick connect to change impedance a little.

12 meter (1st scan 20 - 30 MHz, 2nd scan band specific)
- - -
15 meter (1st scan 20 - 23 MHz, 2nd scan band specific)
- - -
20 meter (1st scan 13 - 15 MHz, 2nd scan band specific)
- - -
40 meter (1st scan, 2nd scan band specific)
No broadband scan
- - -
80 meter (1st scan 3.4 - 4.15 MHz, 2nd scan band specific)
- - -
Mast Only (1st scan 1 - 181 MHz, 2nd scan 2 meters) Guess I will have
to try this on my 2 meter rig.

If you have any graphs that could be added to
this site please send them along. I'll post and credit your
information.
