CAROLINA WINDOM 40

Record Breaking Performance

Used to set two "Miles-Per-Watt" World Records

4,3000,000 miles per watt. Larksville, PA to Raleigh, NC on .000096 watts.
Accomplished by Fran Slavinski, KA3WFT and Paul Stroud, AA4XX


Record Breaking Performance all the time. The CAROLINA WINDOM 40 is used by DX stations all over the world.
It's a 66 foot, multiband powerhouse! It is DXpedition proven and you get the same pileup breaking results.
If it's results you want, choose the CAROLINA WINDOM. DX'er or casual operator, you can't put a better, simpler wire antenna system in the air.

* Based on user reports and field evaluations, and due primarily to low takeoff angles made possible with the CAROLINA WINDOM's Vertical Radiator

* *CW/SSB duty-cycles only. This antenna is not rated for AM, RTTY and other high duty-cycle modes.


The CAROLINA WINDOM's radiation pattern is different from simple dipoles and other similar antennas. Tests have shown that the CAROLINA WINDOM 40 far out performs conventional antennas under similar conditions. Its unique combination of horizontal and vertical radiation components account for the exciting performance that outclasses its competitors. The radiation pattern of the CAROLINA WINDOM 40 is optimized for the upper bands.


To give you an example of this antenna's capabilities, the very first contact I made with a CAROLINA WINDOM 40 during testing was a CW QSO with 3W8CW in Viet Nam. That was a nice surprise!

This antenna is a record breaker. The CAROLINA WINDOM 40 was used in the 40 meter "miles-per-watt" record of over 4 million miles-per-watt.

Ground Space Needed


Configuration vs. Length Required

Flat Top: 66' Inverted-V @ 25' 51' + depends on height of end supports

Inverted-U @ 30' Total 41' short leg bent 5' long leg bent 10' Sloper @ 40' 58'

Sloper @ 60' requires a space of 40'

General Mounting Requirements

Mounting height of vertical section: > 25' Minimum recommended angle between legs = 126 degrees.
Minimum height at ends = 8' Absolute minimum angle between legs = 90 degrees.

Recommended configuration

Flat-top, suspended between two tall trees located > 70' apart.


Coax Length 86 feet of RG-8X or other 50-ohm coaxial cable is recommended for the lowest SWR readings. Any length may be used in most installations.
