      • ALIENTECH DUO II booster can not only effectively stretch the signal distance of a 2.4G drone, but facilitate storing and use given its small size. The function of Quick release saves your take-off preparation time to the greatest. Inside the booster, here are two 18650@2500 mAh rechargeable lithium batteries, which can be used continuously for over 300 minutes each time.
        • This product is developed specifically for 2.4 GHz and 5.8 GHz frequency bands. 2.4G is compliant with the IEEE 802.11B/G/N standard and 5.8 is a bidirectional power amplifier that complies with the IEEE 802.11A/N standard. The product matches frequency spread techniques such as direct sequence (DSSS) and orthogonal frequency division multiplexing (OFDM). Using TIME DIVISION DUPLEX (TDD) fast microwave detection technology and linear power amplifier technology greatly expands the wireless RF communication distance while keeping the transmission rate of 802.11B/G/N wireless devices unchanged.

Antenna Prce

What's made the Antenna go from $200, to $600.00-? 300% increase in price for $20 in plastic ? Good thing theres enough dumb individuals to pay that price.

Mark Dunn (Philadelphia, US)
Still Testing.

I sent my response back on February 28th. and gave it a 5 star rating. I love the service, and the antenna seem to be a little different than before. I still testing my flights in different places.

Dennis Lempar (Boerne, US)
Alientech Dual Frequency Omni Directional Antennas-Junk

Will not hold position. These antennas are not worth the money because they do not hold a tight grip and keep falling down and end up pointing toward the ground.

Hello Dennis, I'm sorry these aren't working for you. These use a qma quick connection. Which means there's no threads to tighten the antenna down.

As discussed, if you're not a fan of how these antennas work, the alientech amplified antenna is what this mod is made for and won't spin in such a way.

As the other option, you're more than welcome to return them for a full refund. I've included a prepaid return label for you to send these back to me.
