UWB Ultra Wide Band 1.35GHz-9.5GHz Log-Periodic Directional RF Antenna with SMA Connector

I haven't measured the gain or return loss but I have gotten these working for data transfer between SDRs. Great product for the cost.

Excellent. Works Great.

nice product.

This product is assembled with very low quality solder connections which do not hold well. If these connections break, as they did for me, no signal can travel through the antenna. An antenna without any transmitting or reception is bad value for the money.

Experimentation

I* ordered two of these to have a matched set. They do not match, one SWR oscillates, the other has a couple of flat spots but they don't even look like the same antenna.

Garbage costs 8 bucks. Total money waste. (Best VSWR at 1.6GHz but still not that good)

Item works good for directionality and is durable. The price is right too. Used on a portapack with the looking glass feature and you can clearly see which direction various signals are coming from. Will order a backup.

exactly what my radio needed! compact, precise, well made!

Definitely much lighter for the MFD AAT servos to move this mini yagi antenna.

This product description clearly says “N connector”, but now it’s arrived, it turns out to be an SMA connector, and thus useless for my purpose. Very disappointed and will have to return.

A classic design with sigma/tau of 0.135/0.81, with predicted frequency coverage from somewhat below 2GHz to 10GHz. The connector is SMA, not N. The center feed at the end of coax was broken when received but fixed with a bit of solder.
