A Plumbing Penetration Should NOT Be Used For Calling The Mother Ship.
Plumbing penetrations are an integral part of the plumbing system.
They are to release pressure from a plumbing drain system. When solids and liquids enter the drainage system of your house they have volume. The space required for that volume needs to be accommodated for. It is handled by the release of air from the plumbing vent. The same volume that goes in, comes out, in a different way. That makes things pass through the drain system smoothly, and without a glub glub (technical term).
Oh, the "air" that comes out contains sewer gas, which is why the plumbing penetration is ON TOP OF THE ROOF! You don't want that gas inside the house! It, um, smells bad. It is harmful.
Look at your roof. You will see one, or two or maybe three plumbing vents. If you go up there and, well, and experience up close what the vent discharges (especially while someone is taking a shower) you will understand that you want that "air" discharging high up and far away.
What plumbing vents are not used for:
1. A telescope - really, it won't work
2. A gun - you will not build up enough pressure
3. An ashtray while you are taking in a romantic rooftop view of the sunrise or sunset
4. A holder for a 15' tall radio antenna so you can call the Mother Ship
We all know how important it is to call the Mother Ship.
I would recommend an aluminum hat, using the special implant they gave you when you visited the Mother Ship, or, in a pinch, piecing together something from materials at hand. That's how ET did it. I saw him do it!
But a plumbing penetration is plastic. It can break and let sewer gases into the attic. It can move and cause a roof leak. It is not intended as a base ... for anything.
The key word in the term 'plumbing penetration' is the word "plumbing." An antenna is not plumbing.

My recommendation: just sayin'. See the photo above? Don't do that. Don't do that. Don't do that.

Yes, I guess this is the opposite of a "best practice."
Good morning, Jay..... funny post.... but not so funny if that vent breaks or cracks under that roofline....
It might be in the Mother Ship Best Practice manual Debbie.
Barbara - I had to post it even though I do like those sunrise and sunset views.
I suggested this post. I bet you see everything! lol I especially liked the "don't do that" chant at the end.
You have to wonder who thought that was a good idea to bolt something to it. Like the vent was put there for future underterminded use or something?
Thanks Chris. I laughed when I saw it, thinking it would make for a fun post one day.
What do you mean, undetermined? What a perfect base!
They live among us Jay. Can't stop them and it is what it is.
I think you're right, James. And there wouldn't be so many movies about "them" if they weren't here.
I have no words..I just....
What goes on in these people's heads? Anything?
I'm sorry Suzanne, but communication is just too important to leave it to those who don't understand.
You don't understand.
How about the chimney? I have seen that done, but not in a long time.
They shouldn't? Is that why I have gotten no message back?
I texted the mother ship, they are in agreement Jay. :)
Oh gee....looks like multi tasking ...
Maybe the chimney didn't point the antenna at the right star, Jim.
Charlie - as I recall one of the things in ET's message machine was the garage door remote. And an umbrella. That may be your problem.
Good to hear Tom. They do smile down at me sometimes.
To be sure S&D! This guy was good!
Hi Jay: LOL.. This is a serious matter but I could not help chuckle. ET phone home!!!
Too funny but educational.
This one is all to common, another case of Home Depot weekend warrior project.
Sometimes people do things out of ignorance; sometimes laziness. Here it is a toss up!
Enjoyed your way of making a very valid point. Used to see this often but since internet and cable we don't see that in our area much anymore.
Well, they probably got the mounts from the Internet entrepreneur, Billy Bob
But, but, but... that thing was sticking up there. It looked like a good place to anchor something else.
Maria - I see this from time to time and thought I'd teach something and have some fun with it!
Tray - the ham radio company may have even suggested that to him!
Gary - no matter. It's coming down now!
Keith - I happen to know two ham radio guys in my neighborhood! It's a different thing altogether.
Ed - that could be. Or that shack with the electonic and radio equipment...
It does look that way Marte! But alas, no fly-o. That's perfect Spanish.
Great lesson about plumbing penetration, so thanks for enlightening me.
Another great post, Jay. At least the plastic will keep it from grounding into the rest of the plumbing. Nice lightening rod!
Thanks for sharing,
Bruce
And this was a sarcastic and funny one Kimo!
Thanks Bruce. That antenna could in fact become a lightning rod.
I'm guessing that they moved it over there after the brick chimney that it was attached to crumbled for some "unknown" reason.
Yea, it is truly said that you can fix ignorance but stupid is here to stay, amen.
Just the thought of Sewer Gases in the house should get us all to be careful about how we treat it.
That crumbled when the Mother Ship zapped it with a laser Marshall. Actually this is the same house as my flashing post a couple of days ago!
Gene - what's a little sewer gas among friends?
Jay, I have to admit that I have never seen a waste vent used as a base for an antenna mast.
Learn something new every day...
Well John, hopefully this makes your bucket list.
Jay: And here all this time I thought them thar things were retrojets to keep the Earth spinnin' particularly with this wierd weather we've been havin'!
Norman - shhhh.
The weather is just a cover.
Wow - I'd hate to see the "reaction" of using that plumbing vent as an antenna! Interesting and informative for every buyer!
The antenna there now is 15' high, Jan! How fun!
Jay, as usual you've got a very entertaining way of getting your point across. Hope you don't mind me reposting it on my Manufactured Home Group. This is very relative info. BTW, I would love you to join and contribute to my group anytime:
Thanks John. We try to inform!
My how creative the owner was, "a real space shot" as they say! good one!
Thanks MaryBeth. Up periscope!
