I'm a satellite guy - not a radio guy - but I need to build an outdoor antenna for NOOA broadcast reception (162.400-162.550MHZ) for a weather warning station I recently acquired.
The existing unit has a telescoping antenna and an external antenna RCA type jack. If I take the unit outside about 35' away I can lock on with no problem - but no lock where the unit needs to sit inside (or anywhere else inside).
Any recommendations for sites? Google search wasn't much help. Dimensions? Material? Any hints?

Yes the copper pipe ones are most common, bit obtrusive for the bedroom or living room 
If you use the 300 ohm line type the thin conductors narrow down the passband a bit and helps filter out out-of-band rf that might overload the weather radio receiver. Remember to change the dimensions slightly for the shorter wavelength compared to the ham 2m band.. I suppose one of these antennas with a good feedline would work well as a marine band antenna too...

Well, I used the on-line dimension calculator set to 162.475MHz (middle of the NOAA range) built it exactly to specs - and it didn't work worth a darn. Even tried moving it around and on top of a big ladder. The 1/4 wave ground plane (Antenna-Stein) worked great in the same spot.
Went over all the calculations again, measurements and all solder points - no joy. Plugged in the 1/4 wave using the same line and it worked just fine.
Now I'm really confused!

But.....if you like Tulsa King....looks like you would probably like this as well. I don't mind spin-offs as long as they don't involve a sassy niece who moves from the big cityAnother Tulsa King spin off.
I thought I would come here and find lots of complaints about the update to the dish anywhere mobile app, but am not seeing any. It used to look just like the desktop webpage. Now you can no longer filter by sports channels or movie channels. Plus that they made it look like a big button telephone and you see fewer channels in the screen which requires more scrolling. Yes I realize you can look at sports then select which sport you want to look at, I just liked being able to see all sporting events in the guide with all other channels being filtered out. Am I alone in the wilderness on this?

Anyone else watch this show? Any guesses as to what was in the box Gibbs gave to Abby that was on her desk? It look liked it was glowing.
I also heard that someone was leaving the show at the end of this season. Any guesses as to who thats going to be?

Tony as the director.
Would you rather have LaRoche ???Tony as the director.
No. Bring in someone new.
Tony is not serious enough for me. Parker is too close to the team and Tim is too young to take over IMO.
I don't think Tim and Tony are that far apart in Age ...No. Bring in someone new.
Remember what Tony said to Tim when they first got back together ...
Tony said: I am the New Tony, Tim .... (something to that effect)
Tony has changed, he's been running his Security Business ... I'm sure he has grown up.
Give it time ... your judging the New Tony from the old Tony.
It sounds like Tim won't be around the Team much longer either.

Might be worth a watch when it comes out. Looks like typical big corp against the little guy movie BUT....there is a reason this plot type is so oft repeated, it draws audiences.

If you're going try to read / listen to the book (can't recommend the audio book enough) before this comes out, I'd avoid trailers.
Trailer below, spoiling it to make sure you read the above bold message first. The book / audio book are fantastic. Go into this blind if you can IMO!
Kind of disappointed at how much they show. A lot still to see, but man, some good reveals in the book that are just served up here.

Browns lose a close one with... The Jets. That is a classic Browns loss (granted, any loss is a classic one it seems). 49'ers, Vikings, and Chiefs remain undefeated. The AFC north have a three way tie at 3-2 for second place.
A big win for the Patriots, and they are now 3-2.

I had quit watching this show years ago because I ended up more annoyed than entertained. Well......I'm STILL more annoyed than entertained. I DO find it interesting to see how things work behind the scenes at many businesses. What annoys me is how utterly out of touch CEOs are with the companies they run. At the end of almost every episode the head of the company is amazed at how hard the employees have to work and many times have to work around impossible guidelines set forth from headquarters.
I found this one interesting because the new CEO had big plans for this company, Muscle Maker Grill, and it looked like the stores were all pretty busy. Recent history hasn't been good to this company however. I bet the covid lockdowns were the real killer.
