Product Details
Brand: Palomar Engineers
Effective Frequency Range (MHz): 100 MHz-500 MHz
PEP Power Rating (watts): cable rating

Combo split bead kit for dual band antenna like 2 meters/450 MHz (J-poles, dual band verticals, etc) - 4 beads covers VHF and UHF band. Each set provides over 500 ohms of common mode resistance to keep antenna current off the coax and on the antenna for better radiation pattern and less coax radiation which can cause RFI to nearby electronics.

Simple to install at antenna feed point - just snap on!

Simple, effective and cheap solution - buy it now!

These impedance transformer kits have been designed for the Do-It-Yourself (DIY) enthusiast and Instructor workshops on baluns and ununs for antenna matching and RFI use.

The impedance transformers are classified in ratios of 2:1 (100:50 ohm) to 16:1 (800:50 ohm).  The outputs can be configured as balanced (Balun) or as unbalanced (unun) with respect to the inputs which are considered all unbalanced coax at 50 ohms.  All impedance transformers are designed for 1.8-31 MHz unless otherwise specified.
