[BACKGROUND]

A Plain Radiator and Nothing Else!
All-Band Vertical Antenna: T-25/S

Frequency-Independent 3-30 MHz -25ft/7.5m high
10-12-15-17-20-30-40-80 m
Plus all frequencies in between!

Best of all: the "Capture Area" of the 25ft. radiator is active on all bands! The T-25/S becomes...

on 10/12 m..........a 5/8 wavelength radiator +/-
on 15/17 m..........a 1/2 wavelength system +/-

on 20 m...............a 3/8 wavelength antenna +/-

on 30/40 m..........a 1/4 wavelength radiato
r +/-

75/80 m: the T-25/S works like a "Mobile Antenna" or better but it covers the full bandwidth. Efficiency on this band depends on space for radials.

  • No Radials Needed 10-40m!
  • No Traps - No Loading Coils - No Tuning Required
  • Typical SWR 1:1.5 at Full Bandwidth
  • 200 Ohm Feedpoint Impedance - 50-Ohm Coax Feedline
  • 1:4 Feeder Transformer (Included in Price)
  • Full Legal Power 1.5kW Out, Continuous
  • Rugged Self-Supporting Radiator S/S Hardware
  • Wind Survival Rating typ. 80 mph (130 km/h)
