A special Application of the Bobtail Curtain

The CAROLINA WINDOM® Short ™ Antennas

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

The CAROLINA WINDOM® Short™, previously known as the CAROLINA WINDOM® Beam™, 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.

CONFIGURATIONS for all CAROLINA WINDOM® Short™ models

FLAT-TOP

This is the design configuration for a CAROLINA WINDOM® Short . You need two supports (trees, etc.) separated by the appropriate distance. Be sure to keep the vertical elements away from metallic objects.

INVERTED-V

You may install your CAROLINA WINDOM® Short™ as an Inverted-V but the angle must not be too sharp. 120 degrees is the acceptable minimum. Element spacing will be compromised if a smaller angle is used. The recommended configuration is a flat-top.

SLOPER

There is no problem if one end of the CAROLINA BEAM™ is higher than the other. Just let the Vertical Radiators fall as perpendicularly to the ground as possible.

RECONFIGURABLE

Reconfiguring a CAROLINA WINDOM® Short™ to a CAROLINA WINDOM

A very special feature of the CAROLINA WINDOM® and CAROLINA WINDOM® Short™ antennas is that they are field reconfigurable. This means that you can easily convert your antenna from the various CAROLINA WINDOM Short configurations into an antenna with characteristics similar to a CAROLINA WINDOM®. If the CAROLINA WINDOM® Short's™ pattern is too HOT for your operating style, you can change the dimensions of the vertical elements or even turn the CAROLINA WINDOM Short back into a full-size CAROLINA WINDOM®.
The CAROLINA WINDOM® Short's™ special, new DMU is backward compatible.

A Better Idea!

The CAROLINA WINDOM® Short 80™ and CAROLINA WINDOM® Short 40 are super-hot, low angle radiators. The CAROLINA WINDOM® 80 and the CAROLINA WINDOM Short 80 have different radiation patterns. One will usually be better then the other. It all depends on the propagation path and angle. Generally, the CAROLINA WINDOM Short antennas (formally known as the CAROLINA BEAM) have the edge on the long-haul DX while the standard CAROLINA WINDOM is as good or better on other propagation paths. You have your choice of radiation patterns depending on your operating style and location. It only takes a few minutes to make the change configurations. Try all the configurations and see which works best for you.
