Hello Derek, Not only does the 3110B have a balun, but it has a well designed one. We originally used another Bicon, but switched to the 3110B several years ago and have been very pleased with the consistent measurements in various geometries (horizontal, vertical, different distances). We were led to this choice by comments in this forum. Hope this helps. Regards, Don Umbdenstock Sensormatic

My existing configuration ( for education purpose) of radiated emission test is connect the EMCO bi-conical antenna, Model 3110B( 30M to 300MHz) antenna directly to the amplifier and then to the spectrum analyzer, I read some books it should include the Balun when feed into the antenna, is there anyone know where to buy or how to build the Balun, and any negative effect if without balun, thanks advance for any help.
