Super-Elastic Signal Stick – Dual Band 2m/440

Description

Please make sure you order the correct connector for your radio!

These are hand-made, ultra lightweight, and nearly indestructible antennas which outperform the stock antenna your handheld radio came with by a significant margin. Originally designed to use as a fundraiser for a youth group, sales from these remarkable antennas are now the primary source of funding for our free ham radio study website, https://hamstudy.org.

These antennas have changed many times over the years; the current versions have black 3D-printed covers over the connectors and clear / GITD tips. Custom colors are available when ordering in groups of 50 or more at a discounted rate, email us for more information.

Features:

• Dual band – 1/4 wave on 2m (144-148Mhz) and 3/4 wave on 70cm (440-448Mhz)
  • SWR has been measured as low as:
    • 1.3:1 @ 146Mhz
    • 4.7:1 @ 220Mhz (not recommended to use)
    • 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.

• Made of Nitinol, a very resilient and ridiculously flexible nickel-titanium alloy
• Extremely light-weight — reduces connector strain on your radio!
