One of the most popular antennas today is the end fed 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 weighs under a pound, yet, with the 71 foot included wire, can work the 80-10 meter bands easily with the built in antenna tuner of most current day transceivers.
The key to the antennas success is the matching network interface between the long wire antenna and the coax feed line to the transceiver. Palomar Engineers employs a dual core matching system that offers wide bandwidth (1.8-61 MHz), 500 watt PEP rating, and a connection for a counterpoise or ground if desired, and a SO-239 female coax connector for easy attachment of coax cable (50 or 75 ohm is ok).
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.
We sell the Bullet matching unit separately so you can add you own wire type and length (see table of suggested lengths below) or you can purchase a complete antenna system including wire, end insulator and support cord. Available as the Bullet-9 (1.8-31 MHz) or 9LF (.2-30 MHz) for VLF use.
For best results we recommend that the coax feed line be at least 1/4 wavelength on the lowest operating frequency since the coax braid is used as a counterpoise if you don’t use the external counterpoise terminal on the matching unit. We also recommend a feed line choke at the end of the coax feed line near the radio to prevent RFI common mode current from interfering with the radio. .
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 (see typical configurations on next page).
Additional Typical Antenna Configurations:
Antenna Length Modifications: For best results, chose a length from the table above as these lengths will form a non-resonant antenna for the amateur bands indicated.The antenna length should NOT be ¼, ½ wavelength on any frequency that you transmit as the impedance will be very high (or low) and will not transfer through the matching unit at a favorable impedance to your antenna tuner.The theory of the antenna length is to make the antenna non-resonant on any amateur band so that the impedance at the antenna side of the matching unit is in the range of 200-600 ohms and when divided by 9 will be in the range of your transceiver antenna tuner.
Any length of 50 ohm feed line ok (over 35 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.Use of one or more ¼ wavelength counterpoise(s) connected to the ground post of the matching unit may also improve antenna efficiency and reduce SWR on certain bands.The first counterpoise should be installed under the horizontal portion of the antenna for best results
Use a good quality 50 ohm cable adequate for the power level of your station.The Bullet-9U matching unit is rated for 500 watts PEP for SSB and 250 watts CW/Digital. 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 1/9 of the RF impedance on the antenna terminal of the matching unit (if the antenna impedance is between 200-600 ohms).
Bullet Antenna Configuration Notes
Testimonial:
Just wanted to drop a line and let you know how impressed I am with my BAS-71 kit that I picked up at my local HRO. I'm able to work every single HF band, 6-160m and most of them without my TS-590SG's internal tuner! (Amazed that I can now work 160m!) Simply configured as a sloper and I don't even have the recommended length of coax, I'm short by about 5-10ft. I will definitely recommend your products to my ham buddies! I will be buying another one of your end-feds for portable ops.
73!

While I’m not a competitive contester, I’ve always enjoyed putting in a few hours during the CW Sweepstakes each November.This year family commitments limited my availability to Sunday afternoon.
However, it turned out that I was almost precluded from participating at all.Just before the contest, the balun on my trusty old G5RV bit the dust.
Fortunately, a few years ago, I acquired a Palomar Engineers “bullet” antenna for portable and Field Day use.Our informal FD group used it this year, along with several other antennas.We were able to raise it to about 45 feet, overlooking the Pacific Ocean, and it worked well.
I immediately thought of deploying this antenna as a temporary measure to see if I could participate somehow in Sweepstakes.I climbed out my second story window onto a patio cover, and hung the balun of the bullet antenna on a hook and connected the coax from the ailing G5RV.I tossed the 55 foot end fed wire off the patio cover, made a 90 degree turn around the avocado tree, and tied the end to the top of a 6 foot fence.The highest point of the antenna was perhaps 15 feet off the ground.Not the ideal setup for a major contest, especially during these poor propagation times, but it was the best I could do.
Without a counterpoise, my transceiver’s built in tuner loaded the antenna on all bands, 80 through 10, even though the manual specifies a longer wire for 80 meters.
The results were surprising:In less than 3 hours of “search-and-pounce” operating, I worked over 100 stations in 55 sections, most of them on the first call.Most were on 20 meters, with a number on 40, and even a few on 80 and 15.Remember, the maximum height of the antenna was only 15 feet!
While it’s unlikely that this setup could win any awards, especially in a busy, competitive session, it certainly saved Sweepstakes for me this year.
I plan to use the “bullet” on my occasional/portable operations.Its lightweight and compact size, ease of deployment, and non-critical configuration makes it a natural for this type of use.
In addition, it’s a solution for those in need of a “stealth” antenna for antenna restricted areas.The wire can be extended in a moment or two, and coiled up at the end of operations just as quickly.
Many of us, even those with modest stations, have a “backup” rig to get on the air quickly in case of unexpected equipment failure.I never gave much thought to a “backup” antenna, because my simple G5RV provided excellent reliability for many years of service.
One of Murphy’s Laws declares that equipment failures happen at the most inopportune times, and it certainly held true for me.I was lucky to have an easy to erect antenna when I needed it. Do you?

Christmas lights or yard lights with switching DC power supplies are often the RFI source and a clamp on ferrite bead on the AC AND the DC side feeding the lights is needed to help suppress the switching power supply RFI noise. Suitable snap on beads are FSB31-1/2 for the 1-250 MHz range.
We have also had reported wireless HDTV boxes, and FOSCAM and AMCREST security camera systems causing RFI to garage door remote openers. Use our Garage Door Opener RFI kit to suppress the interference to the opener (VICTIM) – you need one kit for each opener. Maximize the distance from the camera to the openers may also help. Additionally shield cable to the garage door sensors may be needed depending on severity of the camera RFI.
Obvious Tech Note: make sure your remote batteries have enough energy to activate the GDO or the signal they transmit may not be large enough to over ride the RFI signal, but a fresh battery may be able to overcome the weak RFI source and allow the GDO to operate correctly.
