Maybe they have redesigned the solar shield from the one I have, but I have the exact opposite problem in that its hard to pull the lightning sensor out to change the batteries. Mine is very snugged and secured.
I felt that way when I first installed it.
I always make sure to push the lighting sensor all the way into the solar shield until the two center plastic tabs click over the sensors handle.
When it happened the first time I didn't think I had gotten it securely attached after the last battery change.
When I put the replacement sensor in, I took extra care to make sure it seemed like the tabs engaged.
I live in an area with high winds, Even though the assembly is protected from some directions, wind is probably a factor.
Sometimes what I have done with using their radiation shield is I attached a wire tie at the bottom through the holes diagonally if I thought a sensor could fall out. Just an idea. I have never owned their lightning detector. Just an idea.
Yes, after the first fall out I should have done this.
Interestingly, I use the Acurite shield to house two of my Ambient Weather sensors ... the WH31L lightning sensor and a WH31E temp humidity sensor. Both of these sensors are light weight with only 2 AA batteries each. I have the temp/humidity sensor hanging from the center hook of the enclosure and the lightning sensor attached to one of the side vanes with a small zip tie. So far it has worked well for me. I got the Acurite shield instead of an Ambient shield because it is inexpensive and its shape allowed me to fit both sensors. This thread shows some pictures of the installed sensors: https://www.wxforum.net/index.php?topic=42649
That's interesting. I also use a bunch of Ambient Weather 433mhz sensors the F007TH (and the indoor FT012TH). They are relatively inexpensive and have 8 "channel" settings.
I had looked into the Ambient shield because of how difficult the F007th is to mount -- it doesn't have a hanger, only a tiny/shallow hole. I was surprised how expensive the Ambient shields were at the time. The Acurite shield seemed like a pretty good value.
