Super Bullet 50:50 (1:1) HF Balun + Optional Dipole Kit - .1-61 MHz, 5000 Watts PEP, up to 60 dB noise reductionProduct DetailsUPC: Does not applyBrand: Palomar EngineersMPN: Bullet-1B-5000EBPEP Power Rating (watts): 5000Common Mode Attenuation (db): up to 60 dBEstimated Insertion Loss (db): .1Input Connector Type: SO-239Output Connector Connector Type: Side EyeboltsNew improved version now goes down to 500 KHz (25 dB common mode AM Broadcast band suppression) and up to 61 MHz < 2:1 SWR. Choose Balun only or add optional dipole wire kit (wire, Insulators, Spade lugs for attachment to balun - assembly required). Center insulator and Balun in one case - 1/4" stainless hardware and 5000 real watts rated!
The SBullet-1B-5000EB is a multi-core current balun with built in feed line choke offering up to 60 dB (on 40 meters) of common mode current rejection (plenty for most applications) to keep RFI off the coax outer braid during transmit operations. The SBullet-1B-5000EB is housed in a waterproof PVC enclosure that is lightweight yet robust in features and makes a great high power antenna feed solution for dipoles and other balanced antennas. Halyard hoist at top of balun for convenient attachment point. Input is via SO-239 coax connector and output with dual side eye bolt output and wire strain relief. Rated 5000 Watts PEP Watts from .1-61 MHz. SBullet-1B-5000EB weight is 2 pounds.
This balun/feedline choke keeps TRANSMIT RFI off the coax outer braid while transmitting. If your station suffers from common mode RFI noise on RECEIVE, then use one of our Common Mode Coax Noise Filters (such as the CMNF-5000) that suppresses common mode noise on RECEIVE operations.
Make a FAN DIPOLE using optional dipole kits (e.g. 80/40 would use extra 40 meter dipole if you chose the 80 meter dipole lit for this listing).
NOTE: We rate our Bullet baluns (and ununs) VERY conservatively at 5000 watts PEP with a 50% duty cycle. Some manufacturers selling low cost baluns may use a 5% duty cycle for their PEP rating to make it appear you get a higher rated balun for a lower price, but you may in fact be getting be getting less. Their 1500 watts PEP really means 750 watts continuous or 1500 watts at a 50% duty cycle compared to our 250 watts at 50% duty cycle. Our baluns typically cover a larger frequency range under 2:1 SWR which make your transceiver happy and probably will last longer with less electrical stress.
Remember we over engineer our products, to out perform our competition - just compare the weight 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.

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.
