DUAL 144/430MHz Dualband 41-Element (13/28) Yagi

DUAL 2m70DX41-2conn - 2m 13 element + 70cms 28 element (code 1391)

Ultimate DualBand 2m,70cm Yagi Antenna Two Connectors

Awesome gain on both 144 and 432 MHz for super weak terrestrial contest or EME signals. Ultimate design with full 3D Electromagnetic Simulation Software. Not with EZNEC Pro or 4NEC2.

Antennas-Amplifiers Product Benefits

• No tuning antennas
• Before dispatch, we assemble each and every antenna and test antenna characteristics.
• That means you can expect exceptionally good electrical and mechanical characteristics including low SWR across the designed range immediately after assembling.
• No need to move, cut, tune or use rasp for any element to get perfect SWR on intended
• frequency range. Everything is pre tuned.
• Low SWR and superior G/T, F/B and F/S ratios across the entire bands
• Excellent mechanical properties
• High durability, built without compromise

What does 2m70DX41-2Conn mean?

• 2m band: 144 - 145 MHz with low SWR
• 70cm band: 432 to 434 MHz with low SWR
• DX: Intended for use for DX hunting or catching super weak EME signals
• 41: 13 elements on 2m and 28 elements on 70cm band with excellent gain.
• Comparable with two monoband antennas
• 2Conn: Each band has its own connector. You can connect transceiver like IC-9100 on both 2m and 70cm bands with two cables.
