ACS Broadband HF
End Fed Vee Antenna
PATENT NO 4,511,898
Another unique antenna from B & W! Utilizing the same technology as our folded dipoles, the ACS antennas are grounded. They are particularly well suited to usage with the ends mounted directly down to the ground, or on top of metal roofs for base stations. Support this antenna with our MK112 roof top mast. They offer fully automatic, low SWR operation over the entire HF band without need for an antenna tuner/coupler. They are frequency agile, and will operate continuous ALE or frequency hopping. They will propagate excellent NVIS, medium or long distance.
Besides impressive performance transmitting, this antenna design also delivers when it comes to reception. The superior signal to noise ratio and a high impedance terminator allows reading the weakest signals that other antennas would lose in the background noise. You even get automatic static bleed off from wind or thunderstorms.
There are no mechanical parts like relays or motors to wear out, as in some other broadband tuning systems! Ready to go right out of the box, no taps to change, no measuring, nothing to tune. Designed for the military, built to last, priced for anybody's budget. Fast and simple to deploy.
It's Simple . . . It's Reliable . . . It Works!
Why utilize a broadband antenna?
| Frequency Agile
||The new standard for military, government, homeland defense. Hop frequencies at any speed as long as you want, as there are no mechanical parts or active components to wear out. ALE radios allow reliable HF communications in any weather, day or night, without an experienced operator.
||This one antenna performs short, medium, and long haul, NVIS, and ALE. Whatever the mission, this antenna will perform.
||Low cost. Utilize one antenna instead of several. No need for an antenna coupler/tuner. No antenna switches.
||Tune any frequency in the antenna's bandwidth, and have VSWR of 2:1 or better in HF. VSWR of 3:1 or better from 30 - 60 Mhz. Capture weak signals in receive mode. Much better performance than any vertical. Very reliable.
| Simple to Install
||Easy to install as inverted Vee, flat top, or sloper. Just put it up! No adjustments of any kind. No tuning. Completely assembled. No grounds to play with. Support with our MK114 or MK112 mast kits.
| Simple to Use
||Utilize personnel with far less training. No more choosing which antenna to use, no endless playing with a tuner.
Use stainless steel wire for base stations. Use PVC insulated copper for camouflaged or temporary installations.
The antenna is terminated at both ends by ground stakes (not included.). The center of the antenna must be supported approximately 25 - 30 Ft above the ground. A counterpoise wire (supplied) may be necessary to join the two ground locations, especially in roof top or other applications where uncertain ground conditions exist. The antenna is omnidirectional at the lower frequencies, with mostly high angle radiation useful for long distance. From approximately 5 to 15 MHz, the radiation at lower angles increases, and above 15 MHz the antenna becomes more directional in the line of the antenna wire, toward the balancing network. In applications where space is limited, the wire may be shortened without greatly affecting the VSWR, but lowering the radiation efficiency.

ACS-110N - Stainless Steel Wire, N Connector
ACI-110N - PVC Coated Copper Wire, N Connector
This antenna was designed at Barker & Williamson by the request of the United States Government more than 30 years ago. Since then we have supplied tens of thousands of them to the U.S. Armed Forces and many other military organizations including NATO, UN, international disaster relief organizations, emergency management operations, and countless commercial organizations around the world. It is also a favorite among amateur operators. They can be found on every continent in the world, including Antarctica. From the desert, to tropical rain forests, to frozen tundra - we know that they are very tough and deserve their excellent reputation for performance worldwide.
