TZ-230D-4m
4:1 MEDIUM power (500W) HF Balun
The TZ-230D-4M balun is a high performance low loss, 4:1 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. Dual toroidal ferrite cores are used to extend the useable range of the balun down to 160m and all the way above 60MHz, whilst still being able to handle high power, without saturating. Yes, the balun can be used on 6m too.The TZ-230D-4m Balun features include:
Operating frequency
1.8 MHz to 60 MHz (usable to 1.8 -> 90 MHz)
Operating power
250W CW continuous (into a matched load), 500W PEP
Type
Dual Toroidal ferrite core
Ratio
4 :1 (200ohm : 50 ohm step down)
Typical impedance
200 ohm (300 -> 75 ohm with reduced performance)
Thru loss
< 0.10dB (typical 1.8 to 30 MHz) (Better than 0.05dB midband, better than 0.15dB on 6m)
VSWR
Degradation less than 1.1:1 (typical)
The TZ-230D-4Mis not a kit. It is supplied fully constructed with detailed installation instructions and hardware for mounting.
The TZ-230D-4M is an excellent choice for Off Centre Fed dipole, random length wires, Rhombics, terminated Vee Beams, Log Periodics, horizontal loops and other high impedance antennas.
