Bullet 50:300 (6:1) HF Balun, 1.8-61 MHz, 500/1500 Watts PEP, OCF, ZEPP, Folded DipoleProduct DetailsCountry/Region of Manufacture: USAType: NEWInput ohms/Output ohms: 50 in, 300 outFrequency Range < 2:1 SWR (MHz): 1.8-61PEP Power Rating (watts): 500/1500Input Connector: UHF SO-239Output Connector(s): Eyebolt/WingnutTransformer Topology: BroadbandHardware Type: Stainless - 1/4"Antenna Compatability: High OCF, Zepp, Folded DipoleThe Bullet-6B-500 and SBullet-6B-1500 are multi-core core baluns with a compact enclosure (looks like a bullet) enclosure that is physically lightweight but electrically robust and easy to transport for your portable loop antenna solution or permanent installation. Halyard hoist at top of balun for convenient attachment point. Input is via SO-239 coax connector and output with side eye bolt output. Choose your model rated 500 or 1500 Watts PEP from 1.8-61 MHz.
This transformer requires a feed line choke (see related products) to isolate the coax feed line from the antenna. A coax noise filter at the radio end of the coax is also recommended for best results.
Note" Picture shows 4:1 bullet but 6:1 is identical in size, shape with a different label and impedance level is 300 ohms output. N connector option is custom make for each order - please allow 2 weeks manufacturing time before shipment.
NOTE: We rate our Bullet baluns (and ununs) VERY conservatively at 500 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 75 watts continuous or 150 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.
