The TZ-1840 balun is a high performance low loss, 1:1 balun. The balun is supplied with all stainless steel connections, fully sealed in a high impact ABS plastic case and is suitable for boom mounting or sling mounting. A ferrite core is used to extend the useable range of the balun down to 160m, whilst still being able to handle high power, without saturating.


The TZ-1840 is designed to be able to be used in either wire antenna or boom antenna installations. An eyelet is provided to support the balun when it is hung in a vertical situation such as when installed in a wire dipole or inverted vee. Groves in the base of the balun enclosure are provided to assist mounting of the balun to a round tube such as a mast for an aluminum dipole installation or on a boom in a yagi installation. Large cable ties can be used for the boom installation and small cable ties for the wire installations.


The TZ-1840 is not a kit. It is supplied fully constructed with detailed installation instructions and hardware for mounting. The TZ-1840 is an excellent choice for inverted Vee antennas, beams, large quads, horizontal wire or rotary dipoles.
