Stratux ADS-B 3dBi Gain Small Antenna Set – 1090MHz & 978MHz Labeled Antenna Bundle for SMA and MCX-Connected Software Defined Radios (SDRs)

liked these alot, until……
i like that these went right on my stratux aircraft position receiver. being shorter than the originals, they made it alot easier to install in my plane. in fact, i seldom had to even remove these antennas anymore since they fit so well.however, not long after i started using these, maybe 2 weeks, the plastic cap covering the metal threads, split. and it split the entire length of the cap. i never overly tightened these plastic caps. rather, i was careful when tightening since the stratux terminals are also fragile.comparing the plastic cap thickness to the originals, it is about 1/2 as thick as the originals. thats a mistake with plastic, since that alone would easily facilitate splitting. dont know about the plastic material used for these caps.that may or may not have contributed to this splitting.another suggestion: it would help if a mark of some sort was put onto the plastic base above the threaded cap, so you could easily see where the hinge that allows for angling these is. without that mark, it much more difficult to find that hinge for angling.it would be nice if the manufacturer or supplier will consider replacing the 978 antenna for me. but at the least, these need to be made thicker.thanks….. jim

Review
These are about half the length of the antenna that They replaced. They work and are a lot more convenient when I put the Stratux in my flight bag.

Poor quality
Having found the high-gain (i.e. 5 dBi) antennas to be ridiculously long, I purchased the small antenna set. I’ve found them to be entirely adequate in the cockpit, primarily due to strong ADS-B signals in the region I fly.But first I had to install them – that’s where the first issue showed up. One of the antennas mounted without a problem, and had the proper amount of friction to be able to position it without being loose. The other antenna was so tight, that at first I though it was glued with Krazy Glue. Only after a number of rotations it seemed to loosen up a bit; however, it was still tight, more than it should have been.Consequently, I mounted them (hopefully, permanently), and used them exclusively…until about four months in use when, removing my Stratux from the flight bag, I found one of the antennas hanging (see the first picture). Upon investigating, I’ve found that the plastic holding the SMA connector cracked (see 2nd picture), thus causing the antenna housing to separate from the connector.I tried to fix the crack in the plastic, and to re-attach the housing. No joy. Obviously, I am forced to buy a new set. However, I am positive I will not buy it again from the same vendor. Two stars because they were receiving nicely when the antenna was not broken.

Excellent Performance
I’ve been flying with a Stratux since the first release in 2015. As improvements have been made I’ve upgraded cases, antenna’s and SDRs for not only performance but to support the project. I recently replaced the longer high-gain antenna’s with this small antenna set and wanted to report they work just great. I noticed no change in the amount of data received flying up to FL075. And … they make the whole unit easier to tote around if you remove the Stratux from the plane after each flight.
