Introducing the CAROLINA WINDOM Antennas

Outstanding on all bands

The off-center fed CAROLINA WINDOM provides outstanding performance on all bands, including 6 meters and all the WARC bands, 30, 17, and 12 meters. The CW 620 does not cover WARC bands

An alternative to expensive beams and towers

The CAROLINA WINDOM is ideal for those of you who do not use a tower and beam. It's also ideal for those who want a high performance antenna to augment their beam's coverage by adding 80, 40, 30, 17, 12 and 6 meters.

Low Angle, Vertical Radiation Pattern

The CAROLINA WINDOM'S radiation pattern is an unusual combination of horizontal and vertical lobes. This accounts for the excellent performance of this antenna system. Tests have shown that the CAROLINA WINDOM will out perform conventional antennas under similar conditions.

6 Product Reviews

It's a winner!

Easily beats G5RV, Dipoles, and trap antennas.

This fact has been confirmed by six product reviews, DX'peditions and a world record. The CAROLINA WINDOM has always received excellent marks. One review, in WorldRadio, confirms the outstanding performance of the CAROLINA WINDOM in a head-to-head comparison with a G5RV manufactured by another company. That reviewer found the difference to be around 10 dB, band-for-band. You must remember that the G5RV develops gain on several bands above 80 meters, and the CAROLINA WINDOM still outperformed it on every band.

HOW IT WORKS

It's not the OLD Windom. It's new, It's hot!

Some early versions of the Windom antenna used balanced twin lead in combination with a 4:1 balun. Those designs did not have balanced feed, but used balanced twin-lead feedline. Windoms fed with balanced line do not take advantage of the 'Vertically Enhanced Radiation Technique.'

Enhanced Vertical Radiation due to the inverted Vertical Radiator

The CAROLINA WINDOM, on the other hand, takes advantage and improves on the off-center design. In the CAROLINA WINDOM, the current in each of the wire radiator sections is out of balance. Coaxial cable (which is not a balanced line) will radiate when the voltage and phase relationships are not properly balanced.

Special Matching Transformer

The 'Dedicated Matching Unit' used to match the transmission line (coax feed line) to the antenna is a special design that enhances transmission line radiation. Part of the coaxial feedline serves not only as the transmission line (or feed line) but, simultaneously, serves as a vertical radiator. The wire portion of the antenna is the counterpoise for the vertical radiator. The result is an inverted-vertical antenna located high in the air and free of ground losses. It is a very efficient vertical antenna.

Flat-top, Inverted-V

The combination of horizontal high angle radiation and vertical low angle radiation accounts for the excellent performance of the CAROLINA WINDOM both locally and long haul (DX).

Line Isolator

The LINE ISOLATOR effectively separates the transmission line portion of the cable from the radiating portion. Vertical radiator length is predictable and repeatable.

THE SECRET

A 'Line Isolator' is placed in series with the transmission line at a critical point. The Line Isolator provides a large inductive reactance at the insertion point (the action is similar to an RF choke). This effectively eliminates transmission line radiation beyond the point where it is inserted into the transmission line.

So, this is the secret of the CAROLINA WINDOM'S remarkable performance. It's the vertical radiator. It is not some sort of 'black magic' or 'hype' as some speculate, its performance is quite real and explainable.
