There are no official public specifications available for an amateur radio antenna model designated exactly as the "Surmen Z-207A".
However, Surmen produces a very popular, similarly named model called the Z-200S dual-band mobile antenna. If this is the antenna you are looking for, its specifications include:

Frequency Range: 144 MHz (VHF) and 430 MHz (UHF)
Gain: 2.15 dBi (144 MHz) / 3.8 dBi (430 MHz)
Max Power Rating: 150 Watts
Impedance: 50 Ohms
V.S.W.R:

Length: 22 cm (approx. 8.6 inches)
Connector: PL-259 (M-Type)
Materials: FRP (Fiberglass Reinforced Plastic) whip with a stainless steel base
