The CAROLINA WINDOM 40 version of this antenna was used to set two world records on 40 meters. Imagine what you can do with the 20, 15 and 10 meter version of the same antenna.

General Mounting Requirements

† Mounting height of vertical section: >25'

† Min recommended angle between legs = 126·

† Minimum angle between legs = 90·

† Minimum height at ends = 8'

Recommended configuration

Flattop, suspended between two tall trees located >40' apart.

Recommended Coax and Coax Length

RG-8X is recommended due to its light weight and low stress on the antenna components. Any length may be used in most installations.

The CAROLINA WINDOM 620 has an ideal radiation pattern for 20 meters and above. The unusually low angle radiation pattern generated by the Vertical Radiator, in combination with the horizontal elements of the antenna, concentrates your signal at just the right takeoff angle for DX. If you can’t put up one of our larger systems, the CAROLINA WINDOM 20 is the optimum choice. Forget about lossy, narrow band trap antennas. Forget about all the trouble with open wire and ladder line. Don’t even think about using a G5RV. It’ll do OK on 20, but on the other bands, the G5RV is less than exciting.

The CAROLINA WINDOM 620 uses the same principles and techniques as all of its bigger brothers. They all have the big punch it take to get through when conditions are rough. If you can’t put up a beam, then you definitely need a CAROLINA WINDOM.
