End Fed Half Wave Antenna - Discontinued

We have discontinued this antenna due to the fact the End Fed OCf antenna is safer, shorter, and will work all the WARC bands in unlike the EFHW which only works the fundamental and harmonics thereof. Please consider The following alternatives antennas for 40-6 meters):

Our End Fed Antenna part numbers are:

BULLET-8006 (80-6 meters) - 95 Feet Long

BULLET-4006 (40-6 meters) - 55 Feet Long

Bullet-2006 (20-6 meters) - 25 Feet Long

BAS-71X (End fed long wire 80-6 meters) - 71 Feet long

Need a high performance, multi-band, stealthy antenna system that is easy to setup and use? Get the Bullet antenna matcher with the antenna wire, insulator and feed line choke all in one convenient package (great for HOA restricted areas, camping and portable operations, etc.)

Buy 2 - 1 for yourself and 1 for a friend and save!

PAL-EFHW4010-300

(40-20-17-15-12-10 meters with antenna tuner needed on some bands) – 66 feet flexible 14 gauge, insulated wire, dog bone end insulator, antenna wire pulley for ease of installation and RF choke to keep RF out of your radio AND fine tune the SWR on all bands). Adjust length of antenna and position of choke to suit your needs.

We found that a 64 foot antenna length with a counterpoise of 16 feet to the choke provided excellent SWR on all bands as shown - we only needed to use an antenna tuner on some parts of 40 meters. Your results may vary due to antenna your specific antenna geometry and ground characteristics but tuning the antenna length and the choke position is a quick and simple solution to get maximum performance from this antenna.

This antenna is a great stealthy primary or backup antenna and works exceptionally well for apartments, condominiums, homeowner, mobile home parks, RV applications and ARES, RACES, MARS, EMCOMM, NVIS, First Responders and Emergency Preparedness. Compact, Stealthy and Light weight for back packing and portable use.

One of the most popular antennas today is the end fed half wave due to it ease of installation, portability and stealth in various installations. It can be a condo dweller’s only access to the world of ham radio or the best alternative for a backpacking SOTA (Summits on the Air) mountaintop expedition.

The antenna is simple to deploy, folds up easily for transport, and with the 66 foot included wire, can work the 40-10 meter bands easily with the built in antenna tuner of most current day transceivers. Some bands may not even require a tuner if the antenna length and counterpoise choke position is adjusted correctly. (see SWR graph in gallery).

The key to the antennas success is the matching network interface between the have wave wire antenna and the coax feed line to the transceiver.

The antenna can be used as a sloper, “L” with a vertical section and a longer horizontal section, or as a random horizontal antenna between two trees or supports.

BULLET Matching Unit

Our antenna matching network is called the “Bullet” because of it shape and its effectiveness at taking down or contacting distant (DX) stations all over the world under the right conditions.

For best results we recommend that the coax feed line at least 25 feet. We also recommend a feed line choke near radio end of the coax feed line to prevent RFI common mode current from interfering with the radio.

Suggested wire lengths (measured from Bullet feed point):

Installation

For best results raise the Bullet matching unit as high as possible (use a tree or vertical support) and then extend the antenna wire horizontally or as an “L” (horizontal with vertical end drop). The antenna may also be deployed as a sloper with the Bullet matching unit at the top (best) with the wire sloping toward the ground (with the end high enough to avoid contact by humans or animals), or at the bottom of the sloper with the antenna wire rising to a higher point.

Any length of 50 ohm feed line ok (over 25 feet minimum) but longer feed lines over 50 feet may show reduced SWR on some bands due to soil conductivity, nearby objects, etc. Due to local ground conditions, antenna height and feed line length, SWR may vary and an antenna tuner may be required or some bands to bring SWR at end of feed line to acceptable levels. Position a feed line choke (part# SOFLC) 16 feet from the matching unit and tune the wire length and choke position for best SWR on all bands.

Use a good quality 50 ohm cable adequate for the power level of your station.The Bullet-49 matching unit is rated for 300 watts PEP for SSB and 150 watts for CW or digital modes. If the matching unit becomes warm to the touch after transmitting at high power, reduce the power output or the internal matching unit may become damaged.

NOTE: The matching unit output is DC grounded to bleed off static electricity, however it is not RF grounded as the RF signal (at the coax connector) will see approximately 1/49 of the RF impedance on the antenna terminal of the matching unit. The antenna connector is HIGH VOLTAGE (857 volts at 300 watts input) so keep contact away from children, pets, and other people!

NOTE: due to the nature of antenna systems and the modifications many users perform and the transmitter power levels that may be applied higher then the specifications, the antenna systems are NOT RETURNABLE unless they are unused, in the original packing with the original invoice and a return request is made withing 30 days of original purchase.
