CAROLINA WINDOM 40 PLUS
| This antenna
provides improved performance on 80, 40 and 20 meters with a sacrifice in
radiation pattern takeoff angle on the higher bands. For best all band
performance order the standard CAROLINA WINDOM® 40.

|| 50 ohm coaxial cable, RG-8X or Super
240 is recommended
| Matching method
|| Dedicated matching transformer +
| Tuner needed

|| Not required
* Based on user reports and field
evaluations, and due primarily to low takeoff angles made possible with the
CAROLINA WINDOM's Vertical Radiator
|* *CW/SSB duty-cycles only. This antenna
is not rated for AM, RTTY and other high duty-cycle modes.
|* Important: Not rated for AM, RTTY or
other high duty-cycle modes. Power rating is for normal SSB and CW duty-cycles
Exception: At transceiver output
levels, this antenna may be used on PSK-31 and similar modes.
|The CAROLINA WINDOM® 40 Plus has the
same dimensions as the standard, full-size, CAROLINA WINDOM® 40 with the
exception of the Vertical Radiator. In the "Plus" version the Vertical Radiator
is 18' long instead of usual 10' Vertical Radiator of the CAROLINA WINDOM®
40. This improves performance on 40 and 20 meters, but sacrifices some
performance on bands above 20 meters.
If 40 and 20 meters are your bands of
interest, you may want to consider the CAROLINA WINDOM® 40 Plus. For the
best performance on all bands from 40 - 6 meters, then the CAROLINA WINDOM®
is the best best choice.
The CAROLINA WINDOM's® radiation
pattern is different from simple dipoles and other similar antennas. Tests
have shown that the CAROLINA WINDOM 40 far out performs conventional antennas
under similar conditions. Its unique combination of horizontal and vertical
radiation components account for the exciting performance that outclasses its
competitors. The radiation pattern of the CAROLINA WINDOM® 40 is optimized
for the upper bands. The CAROLINA WINDOM® 40 Plus further refines the bands
of maximum performance to 40 and 20 meters with only a slight loss of
performance above 20 meters.
To give you an example of this
antenna's capabilities, the very first contact I made with a CAROLINA WINDOM 40
during testing was a CW QSO with 3W8CW in Viet Nam. That was a nice surprise!
(Let me guess how many years ago that was!)
This antenna is a record breaker. The CAROLINA
WINDOM 40 was used in the 40 meter "miles-per-watt" record of over 4 million
