HOW IT WORKS

The reason for the CAROLINA WINDOM's exceptional performance is its 'Vertical Radiator Section.' The CAROLINA Short 40tm has three vertical radiators.
The horizontal portion of the antenna interconnects the three vertical sections and acts as a radiating counterpoise. The result is a multi- element inverted-vertical/horizontal antenna that operates high in the air, free of ground losses. It is a very efficient antenna.

Can I make my CAROLINA WINDOM into a CAROLINA WINDOM Short 40?

Each DMU (Dedicated Matching Unit) and Line Isolator in the CAROLINA WINDOM and CAROLINA WINDOM Short antenna is optimized for a specific antenna system. A DMU must provide the correct current balance and output impedance to produce maximum efficiency from a particular antenna's Vertical Radiator. The DMUs cannot be interchanged. The same goes for the Line Isolators. In fact, the Line Isolators are more critical since they are used as a tuning element to reduce the SWR in the antenna system. Just bending up a CAROLINA WINDOM means you would give up much of the performance capability of the CAROLINA WINDOM Short.

RECONFIGURABLE

CAROLINA WINDOM Short <--> CAROLINA WINDOM

A very special feature of the CAROLINA WINDOMTM 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.
