Ultimate DualBand 2m – 70cm Yagi Antenna Two Connectors 2m70DX41-2Conn

Supersized 2m – 70cm 41 element Dual-band Antenna 2m70DX41-2Conn
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.

That leads also to another very important detail. When assembled and tested each antenna is complete with all washers, nuts, bolts guy rope supports etc.
When packing all parts are already on antenna without possibilities to “forget” important parts to put in the box. So you will always receive complete antenna what we tested just before dispatching.

Designs that work well in all weather conditions

• 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 2m70DX41-2Conn mean?

• 2m band – 144 – 145 MHz with low SWR on any frequency.
• 70cm band – frequency range 432 to 434 MHz with low SWR
• DX – Intended for use for DX hunting or catching super weak EME signals
• 41 – 13 elements on 2meter 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.

With less than 100 W with this 2m70DX41-2Conn dual band antenna you can work many EME stations.
