новая 100-200МГц ( обрезается и настраивается )

The Schomandl 717758 is a tunable Groundplane antenna for a wide frequency range. • Entire antenna at DC ground potential to prevent electrostatic noise and to improve lightning protection

• Wide frequency range achievable by cutting radials to desired length

• Variable mounting configurations allow feeder cable to be run inside or outside the support pipe.

• Stainless steel ground radials,hardware, and fastenings.
