Description
This Ultimate Dual Band Yagi Antenna features two connectors and excellent gain for 144 MHz and 432 MHz. It is designed with the help of sophisticated 3D Electromagnetic Simulation Software, not EZNEC Pro or 4NEC2. Ideal for picking up ultra-weak terrestrial contest or EME signals!
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?
- 2 m band: 144 – 145 MHz with low SWR
- 70 cm 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 2meter and 28 elements on 70cm band with excellent gain.
- Comparable with two monoband antennas.
- Each band has its own connector. You can connect transceiver like IC-9100 on both 2 m and 70 cm bands with two cables.
