The Bullet-2-1-500EB (500 watts PEP) or the SBULLET-2-1-1500EB (1500 watts PEP) are both multi-core, 2:1 (50 ohm to 100 ohm) baluns plus a 1:1 feed line choke in a single compact (looks like a bullet) enclosure that is lightweight and easy to transport for your fixed/portable.

Very useful for single band horizontal or vertical loop antenna systems. Halyard hoist at top of balun for convenient attachment point. Input is via SO-239 UHF coax connector and output with side eye bolt output.

For multi-band loop antennas consider the Bullet-4-1-500EB or SBULLET-4-1-1500EB

Remember we over engineer our products, to out perform our competition - just compare the weight and frequency range of our baluns to theirs and you will know we put much more into our products so you don't have to worry about failure at a critical moment.


Portable operation is fun but also brings challenges to the radio operator concerning receiver “noise” levels, RF interference from adjacent sources including close by transmitting stations, and RFI from portable generators.  A typical scenario and some suggested Palomar product solutions are shown in the picture below:

Generator RFI testimonial:

Bob 

Received your order in a timely fashion. Tried the generator kit on Sunday & it drops the noise from S9 to S5 and 
took out all the electrical noise.  I may want some more toroids from you at some point for other interference problems
I have  here.

Want to make up your own RFI kits for a particular operation? Here are links to some of  typical RFI solutions used in portable operations:

AC/DC common mode filters

Feed Line chokes

Coax Noise Filters

If you use a computer for logging in your portable operations, RFI getting into computers will often lock up your computer and/or radio and a computer RFI suppression kits may be helpful

Computer RFI Kits

Make your expedition or portable operation a pleasant and fun outing and remember to take along your RFI kits so you have more time to operate rather then to troubleshoot intermittent or noisy receiver conditions.

Portable Antenna Kits

If you need an effective portable antenna which folds up for transport yet is easy to deploy at your operating site, consider the BULLET series of end fed wire antennas.
