HYBRID MINI-BALUN Unique Features:

- Uses proprietary Multi-Bead, Multi-Ferrite technology for maximum power transfer and minimum SWR with properly matched antenna wire

- 100 Watts PEP, 50 ohm SO-239 connectors In, side eye bolts output, 1-61 MHz (usable to 100 MHz) - AKA 4:1 + 1:1 HYBRID BALUN

- Excellent for multi-band, full wave loops, folded dipoles and Off Center Fed Dipoles

- 2-5 times more wider bandwidth and higher power then competing baluns of similar power rating

- Makes a great matching device for portable OCF antennas like our 34 foot, 20-6 meter OCF (PAL-OCF2006) or Loop (PAL-LOOP2006) or BBTD or T2F. For DIY fans use our Loop Wire Kits or Dipole Wire Kits (OCF) to make your own antenna complete.

This balun has a SO-239 input and 1/4" stainless steel side eye bolts output and a top eye bolt to act as a halyard lift line to raise the antenna.

For Higher Power needs use our BULLET-4-1-500EB or BULLET-4-1-1500EB or the square box version in the CB-4-1-1500EB (1.5KW) or CB-4-1-15000EB (5KW)

The high power ferrite impedance transformer series (> 1:1), configured with outputs to act as a baluns (unbalanced coax in to balanced load output) or as ununs (unbalanced coax input to unbalanced load output) are designed for demanding radio transmitter stations that run over 1,000 watts PEP or run continuous modes like AM, digital, RTTY, FM, etc. at high power levels. Radio contest operators, commercial shortwave broadcast, and industrial and commercial stations use these transformers for for a variety of balanced and unbalanced antenna loads. Baluns are typically used for balanced loads and antennas like dipoles, loops, log periodics, and direct feed yagi/beams. Ununs are used with verticals, end fed wires, horizontal dipoles, G5RV/ZS6BKW, Zepps, vertical wire beams, etc). All products are in an enclosed NEMA water resistant box with SO-239 input connector and stainless steel side/top studs with wing nuts or side and top eyebolts. The enclosure box has mounting “side feet” for attachment to a post or antenna boom using nylon ties.
