Title: what are those things?
Post by: DELETED-USERNAME-009 on February 15, 2016, 08:46:03 AM
This maybe a simple answer, and I have had it in mind for a few years with no one to answer. I see these little upside down fire cracker sized cylinders with a 2 or three inch wire coming out. They can be attached to a number of things usually outside on a maintenance shack or on a street light or some sort utility or security concern.. Normally they are grey and the wire comes out of the bottom. I have often thought they are proximity sensing. I cannot guess, and how do they get their power supply?  Thanks  Leonard Garland KC6rwi

It would help if you would snap a picture of one and post it.

if there was one antenna up and one down, it would probably be a wifi network node for internet.

just one, it's probably a sender or receiver on the power company channel.  assuming you see them on utility poles only.  this is "smart power" stuff to help boundary-chart outages and stuff.  most of them in our area look like little yagis if next to a 3-phase line, but there are single verticals on distribution lines.  some could be senders also... there are "summer air conditioning rates" based on switching home a/c off for 15-minute periods, and the signals radiate off those dinguses to the little boxes next to the a/c units outside.

if you are seeing them on pole barn lights, they would be daylight sensors to turn the lights on and off.

could also be little bombs by terrorists, but we don't have a noticeable amount of that here.

thanks..I am going to have to take a picture. basically its about the size of a c battery a tiny arm of metal brings it out about 2" from whatever it is mounted to and a dangling 3 inch piece of wire comes out the bottom..I just searched google images and did not find it..I must take a picture.I've seen them around a public park, even on a utility building,and I saw one on the way to work on a grass medial mounted to a short sign.

yeah...I got that, and it is funny, you know when I posted that title, a tiny voice may have said poat "what the hell is that", and being a first post and not knowing the community at large I skipped the urge. I'll show you, I'll post a picture of one those things.

.... I see these little upside down fire cracker sized cylinders ...

just a simple question,........... if you don't know what they are, how do you know they are upside down? ::)

I read 'I see these little upside down fire cracker sized cylinders with a 2 or three inch wire coming out.' as a description.

Sounds like an auto engine ignition points capacitor.

Being old, I replaced a crap load of those and never saw one with more than one wire.

8P:  The attachment  to the case is the "second" wire or ground.  We're just guessing, right?


Title: RE: what are those things?
Post by: DELETED-USERNAME-009 on February 18, 2016, 01:58:09 PM
I'm beginning to think that this is something the city put up for some sort of monitoring. I have seen them in the city I live, Glendale ca.. TO describe them better,, about 3 inches long, grey plastic tube and from the bottom a single wire always hangs out about 2"or 3" I know I have seen one mounted on a wooden utility shed, also on some decorative lamp posts, and I have even see them on signs on the median of a main road. I wonder if they are monitoring humidity. I will get one or take a picture. Now that I have started this post I must end it.

We're sending Scully and Mulder to the site to investigate......The FBI received a report that a NHG (nerd ham geek) made the initial report.

I am half suspecting that they are the traffic signal preemption devices used to allow emergency vehicles green lights. Do they look like the picture on this page?

The picture would sure help. Remember, a picture is worth a THOUSAND words! You can easily visualize it because you have actually seen it. A good picture will likely solve the mystery very quickly.
There are probably not two people that are visualizing the same thing from your descriptions.

Yes, Yes, K5TED. that is what I see in my city parks and else where, of course my version is a single and yours shown in a double cylinder.
I did make the mistake of not supplying a picture. Now if its not to much  to ask what is their function?

Is that a small wire hanging from them?

Yes, that is a small wire, an antenna maybe.

I wonder if they are remote temp sensors, although where they get power is beyond me...

I have no idea. I just took what you described, Googled "plastic sconce", found one that looked like what I had envisioned by your description, and Photoshopped it in to that picture. Now at least we know kind of what it looks like.

I'm really sorry for the original poster that I cracked a joke regarding the "what's that" and advised finding someone near by to ask... after all, most people aren't technical, hams are, so this was/is the right place to ask. It seems some of the previous replies could also have been interpreted as unfriendly, and I'm sorry to see that the original poster has deleted his account. I hate to think my joke was the straw that broke the camels back. The original poster sounds like a gentleman and a ham, and I hope he will rejoin the forum again. 73 OM.

Eh, if just that set him off then maybe he's better off not posting.  Seems like some emotional immaturity at work.


Title: RE: what are those things?

I just hope he'll rejoin and give us a real photo of the 'thing'.


Title: RE: what are those things?
Post by: VK5EEE on March 03, 2016, 09:44:40 PM
I just hope he rejoins, don't care if he doesn't provide a photo of the "thing" after all it seems it was identified and his description was pretty good as it turns out, someone was able to google image find it. I'm guilty of the same too, I have started a thread about an "unknown mode" and done my best to describe it, but really, I need to record it and give a link to the recording. Would also save a lot of replies that are asking more questions, and requiring more answers. I'm only generally unkind to Digital CW operators  ::)

Let him go.  Guys like that just want the attention by being consoled after getting their feelings hurt.  Next time, it will be something totally different that will get his panties in a twist.

Why are his feelings hurt? He described a thing. I found something that resembled what he described and posted an artistic rendition of such to see if he concurred that it was indeed a valid representation. He did. Now, we need to see the actual thing to do further investigation.

Hard telling, bro.  Lots of odd ducks in the hobby.

I'm guessing that due to their stealthy appearance, they are climate change monitors. If they were larger and more visible, climate change deniers would be plinking them with .22s.

  I believe I know exactly what that is!  My ex girlfriend had a couple of them.  I don't think it would be appropriate however, to go into details about it on this forum.
