Backpacker balun kit

These small, lightweight baluns are perfect for field/portable antenna deployments. The kits are simple to assemble, and can be configured to provide your choice of a 1:1, 4:1, or 9:1 impedance ratio. The dual-core design assures low loss and wide bandwidth. These baluns are easily capable of handling 25 watts SSB and 15 watts CW when terminated with a good feedpoint match, and are optimized for use on the 40-10 meter bands. Weight is 1.7 oz (48g). The kit includes a pre-drilled Hammond enclosure., balun cores, wire, and gold-plated binding posts. A phono (RCA) jack mounts in the enclosure, and a RCA-BNC adapter is included with each order.

The balun file is corrupted. Is there a good one?

If winding your own BALUN for a dipole, consider type 31 or type 43 ferrites when using a transmission line or guanella type winding. Also using small coax instead of bifiler windings will increase the bandwidth of the BALUN. RG-400 is a great option, but there are other coax types that also work well.
