A special Application of the Bobtail Curtain

The CAROLINA WINDOM Short tm Antennas

The CAROLINA WINDOM Shorttm is a DX'ers antenna, but there is no reason everyone shouldn't take advantage of their secret weapon.

It combines the best characteristics of the CAROLINA WINDOM and the 'BOBTAIL CURTAIN' BEAM

CAROLINA WINDOM Short

The CAROLINA WINDOM Short is actually part CAROLINA WINDOM and part Bobtail Curtain (sometimes called a "Half-square" when it has only two elements). It takes advantage of the best characteristics of both antennas. You have the performance advantages of the Bobtail Curtain, combined with the additional performance and convenience of the CAROLINA WINDOM. The CAROLINA WINDOM Short thus takes the lead in simple, high performance antenna systems. It sets the new standard for high performance, all band, wire antenna systems.

The CAROLINA WINDOM Short has three vertical radiators directly interconnected by the single horizontal radiator. It is this unique integration of horizontal and vertical radiation components that accounts for the outstanding performance of this antenna system. An added benefit of this system is the reduced length of the CAROLINA WINDOM Short. The 80-10 meter CAROLINA WINDOM Short 80 is only 100 feet long. At only 42' or 50' in length, the CAROLINA WINDOM Short 40 is as much as a full 24' shorter than a 40 meter dipole.

Add the outstanding performance of the CAROLINA WINDOM Short, its all-band capabilities and convenient coax feed and you have an unbeatable antenna.

PERFORMANCE

I compared the new CAROLINA WINDOM Short 40 (40-10 m) and CAROLINA WINDOM 40 against our reference G5RV system. During daylight operation when incoming signals arrive at high angles, all antennas perform similarly, with the G5RV coming in last. The CAROLINA WINDOM Short 40 was down a bit from the CAROLINA WINDOM 40 due to the CAROLINA WINDOM Short's extremely low takeoff radiation angle. However, at night, or anytime the band lengthens for long-haul DX, the CAROLINA WINDOM Short outperforms the G5RV by a couple of 'S-units,' sometimes more. The improvement depends on direction and distance.

The full-size CAROLINA WINDOM Short 80's (80 - 10 meters) characteristics are similar. Again, it has the advantage on 40 - 10 meters when the bands support long-haul DX. An added advantage is the shorter length, only 100' for an 80 meter antenna.

The phased multiple vertical radiator sections are the reason for the outstanding low-angle, long-haul performance of the CAROLINA WINDOM Short antenna. The three vertical sections generate a very low angle radiation pattern while radiation from the horizontal portions of the antenna provides a medium-to-high angle pattern.

The 10 Meter Surprise

On 10 meters, incoming signals arrive at low angles most of the time. The advantage was always with the CAROLINA WINDOM Short 40. The difference between the G5RV and the CAROLINA WINDOM Short 40 was the difference between hearing a station and not hearing it. It's like switching over to a Yagi. Signals seem to pop-up out of nowhere. The effect is almost more dramatic than the low-angle performance observed when long-haul DX is coming through on the other bands.

Combine this level of performance with the small size and moderate height requirements of the CAROLINA WINDOM Short antenna, and you have an unbeatable multiband antenna. It's the right antenna for both DX and general purpose operation.
