NOTE!
All 4 Antennas are Base Loaded and were tested using the Wilson SO-239 Mag Mount bases as all antennas are compatible with the Standard SO-239 connector on the Wilson Mag Mount bases .
Testing was performed in side by side (all 4 antennas on roof at: 5/10/15/20/25/and 30 miles Parked and at 65 mph & 90 mph using a Transmitter/Antenna Switch.
Testing was also performed with just a single antenna mounted in center of roof for comparison with the vehicle being mobile and parked at: 5/10/15/20/25/and 30 miles.
Testing was performed by recording the mobile signal's from the antennas to the base station's and the base station's signal's to the mobile radio's over 12 different days under different weather conditions.
Mobile Radios used for testing:
SUPERSTAR SS-185EDX (10 & 40) Watts Output
and
MAGNUM S-9-175 (10 & 200) Watts Output.

REVIEW
After testing all 4 of these atennas I found some GREAT points and some NOT so GREAT points.
Both the RM Roadmaster Z-180
and the SIRO SILVER MEGA WATT 4000 out performed both the Wilson 1000 and Wilson 5000 by 2 to 3 S-units on Receive both parked and at highway speeds.
The RM Roadmaster Z-180 also had 2 to 3 S-units LESS Static Noise from power lines than the WILSON 1000 and WILSON 5000 and 1 to 2 S-units less Noise from power lines than the SIRO SILVER MEGA WATT 4000.
Helping with the testing of these 4 antenna's were Corncob / George / CEF#166 and 808xyl / Shirley / CEF#164 on base staton's and BOTH reported a 2 to 3 s-unit increase on Receive with me using the: RM Roadmaster Z-180 and SILVER MEGA WATT 4000 antennas over the WILSON 1000 & 5000 antennas.
The MAJOR + I NOTICED before even testing all antennas is the fact than BOTH the stinger's on the: RM Roadmaster Z-180 and SILVER MEGA WATT 4000 antennas is that they CAN both be LOWERED  without having to remove the antenna from the MAG MOUNT.
Unlike removing the Mag Mount and Antenna or just antenna on BOTH the WILSON 1000 and WILSON 5000 for clearence for car washes, bank drive thru lanes or placing your vehicle in the garage.
My own personal rating for OVERALL for Prerformance and Features.
#1 ~ RM Roadmaster Z-180
#2 ~ SIRO MEGA H-P 4000----------Big Power Antenna
#3 ~ WILSON 1000
#4 ~ WILSON 5000
