TZ-330-4

4:1 high power HF Balun

---

The TZ-330-4 balun is a high performance low loss, 4:1 balun voltage 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 80m, whilst still being able to handle high power, without saturating.

The TZ-330-4 Balun features include:

Operating frequency	3 MHz to 30 MHz (usable to 1.8 MHz with reduced VSWR performance)
Operating power	1 kW CW continuous (into a matched load)
Type	Linear, ferrite core
Ratio	4:1
Typical impedance	50 ohm or 75 ohm (200 - 300 ohms load impedance)
Thru loss	Less than 0.25 dB (typical)
VSWR	Degradation less than 1.2:1 (typical)

The TZ-330-4 is not a kit. It is supplied fully constructed with detailed installation instructions and hardware for mounting.

The TZ-330-4 is an excellent choice for inverted log periodic arrays, Vee beams, rhombics, Off centre fed (OCF) dipoles, windoms, single element quads,  random length wires and other high impedance balanced antennas.
