Tubular feed line chokes (a.k.a. coax line isolators) are convenient for insertion in the coax feed line at the antenna feed point or the station entrance and they include an optional ground lug and static bleeder for attachment to a ground rod. Very useful as coax line isolators along a long coax feed line to break up resonances every 1/2 wavelength. Very wide bandwidth, up to 45db common mode suppression ensures transmitted signal stay on antenna when installed at antenna feedpoint or that common mode coax braid noise is reduced when receiving weak signals when installed at radio end of coax. 500/1500/5000 watt options and various frequency ranges available.
