The only good information I find about that antenna is from an Italian website. Google translates it as follows:
Frequency: 430-440 MHz
Impedance: 50 Ohm
Configuration: 7 / 8
1:1 SWR at band center
Maximum power: 50 W PEP
Polarization: Vertical
Weight: 0.65 kg approx
Dimensions: 60 cm.
Connector: SO 239
Equipped with terminals for
mounting on the wings of support
25 to 50 mm.
Steel bolts.
Relative gain: 3.5 dB.
Looks like a decent small vertical. For 440mhz though, you can find quite a few cophased verticals that really have some serious gain that aren't all that large. That would be worth considering.
