Balun Designs 1:1 Maxi Choke Balun. 5KW Dual Cores. Model 1115dt (studs on
tops). Designed for those who want the maximum isolation and choking across
the full HF spectrum. Building on the original 1:1 design by Dr. Jerry
Sevick, this balun has two (2) cores in a stacked configuration to maximize
choking impedance on HF bands from 1- 54MHz. By utilizing Mil-Spec coax, the
SWR, Transformation and power handling are excellent while providing a
choking impedance that exceeds 10,000 ohms. Check it out at
www.balundesigns.com. This unit is Brand New. Yours for $45 plus shipping.
Balun Design 1:1 Isolation Balun 5KW - Model 1115u. Sometimes called a choke
balun or common mode choke, this 1:1 ratio current balun is the best for
feedline isolation. It has the widest operating frequency range, lowest core
stress and provides the best overall balance of any balun for given cost,
size, and weight. If you have a yagi you should be using one to balance the
power to the driven elements and prevent the coax feedline from distorting
your radiated pattern. If you have a vertical you should be using one to
prevent the vertical element from using your coax as a radial and to
decouple the feedline for reduced noise. Check it out at
www.balundesigns.com. This is Brand New. Yours for $35 plus shipping.
