Signal Stick Super Elastic Antennas

Reviewing the Super Elastic Signal Stick Antenna by SignalStuff

Features:

Frequency range:
- Dual band version – 1/4 wave on 2 meter (144-148Mhz) and 3/4 wave on 70 centimeter (420-450Mhz)
  - SWR has been measured as low as:
    - 1.3:1 @ 146Mhz
    - 1.5:1 @ 440Mhz
    - This SWR chart was taken using a balun to isolate the antenna and a ~18″ tiger tail to stabilize the SWR. Take it with a grain of salt, but it’s fairly accurate as far as it goes.
- Single band 220 version – 1/4 wave on 1.25 meter (222-225Mhz)
- Single band 440 version – 1/4 wave on 70 centimeter (centered at approximately 440Mhz)
Power limits:
- Dual band version: 100 Watts max at 50% duty cycle or 50 Watts max at 100% duty cycle
  - For more information on how this was determined see this whitepaper draft

- Dual band version – Approximately 19″ long
- Single band 220 version – Approximately 12″ long
- Single band 440 version – Approximately 6″ long
