Yeah but a lot of antennas do both. It's just that in the process of making it work for both, the antenna loses reliability with VHF signal apparently.


This probably isn't the place for a VHF/UHF primer but here are some basics (I work in the broadcast industry):

Both have been around for decades. Your parents, grandparents, or if you are an old gently caress like me, yourself, are quite used to this, just with analog signals instead of digital.

The decision around which stations transmit in VHF vs. UHF for the purposes of HDTV transmissions in the US was made decades ago, in the late 90's, and is often dependent on what the station in a particular market was using for analog transmission. Some markets these days have only UHF, which is generally preferred. Many have both. No broad market area that I know of in the continental US uses VHF only though I am sure there are exceptions to the rule somewhere.

VHF operates in the lower frequency band, generally the spectrum between 54-216 MHz (more specifically, certain ranges inside that). The wavelength of these frequencies is longer than UHF and more susceptible to interference, physical obstructions, metal (such as radiant reflectors installed in many houses and buildings in hotter areas, such as the American South) and so on. Said signals have weak reflection properties and as such generally operate best via line of sight. I'm oversimplifying quite a bit here so if a broadcast engineer wants to jump in and nitpick have at it.

UHF wavelengths for HDTV operate in the range of 470-890MHz and as a result are much shorter (literally), reflect much better, and to make a very long explanation short (pun!) are easier for smaller antennas or those with a lot of obstructions in the way to pick up. Again, generally speaking.

The primary cause of poor VHF reception when it comes to modern, practical purposes with HDTV, is small, indoor multi-directional antennas. These can, and do, work, but you better be close to the VHF tower (under 15 miles is ideal if it is transmitting at a good power level...and not all do, depending on local conditions, regulations, cost concerns, and so on). And the fewer obstructions - particularly any metal close to the antenna - the better due to the issues outlined above. UHF has the same general concerns but is much more forgiving overall.

Indoors, a well positioned directional antenna - or at least one that allows you to align the VHF element - with said element properly aligned towards the tower can help. Attic antennas are the next step up, since A) they can be positioned higher, which can mitigate external obstructions B) the elements can (and should) be larger because it's hidden in an attic so who gives a poo poo what it looks like and C) You probably (though not always) will have an easier time positioning it in an ideal spot. Of special note is the aforementioned radiant shielding installed in many attics, particularly down south - good luck pointing an antenna towards a tower with that in the way if it isn't close by and transmitting at high power. In that case many people (and I am one of them) actually find it better to mount it lower in the attic, aligned towards wooden joists/etc. or other spots where there is a gap in the shielding.

Fun fact: the stereotypical "rabbit ears" you still find in a lot of antennas (and were quite common years ago) are for VHF. The shorter "loop" is for UHF. You've probably seen indoor table-top type antennas like this. Newer-style "flat" unidirectional antennas combine both elements (usually), not always with the greatest level of success.

Outdoor antennas are the best, generally, for the same reason as attic except you also avoid another layer of obstruction and in some cases can position it even higher. This isn't always practical, of course. These days it's not practical at all more often than it is for a variety of reasons.

Special note on signal boosters/amplifiers - a common misconception is that these somehow boost the ability of the antenna to pick up signals. Not true. They boost the signal that the antenna gets in the first place. It won't boost what the antenna isn't already getting. It can help in some circumstances with weaker signals that are right on the margin however really they are used to boost the signal coming out of the antenna down the cable. This is useful for long cable runs, or cable runs that go in to a distribution box (in the latter case it may make more sense to power said box, otherwise make sure the power injector is inserted in the cable before it reaches said box).

I.e. if you are installing one of those flat behind the TV antennas and have a 3 foot cable running from it to your TV (or HDHR, etc.) an amp is not likely going to help and in fact can make things worse since it amplifies every aspect of the signal coming in, good and bad, and can distort it.

The TL;DR of all this is check Antennaweb, the Winegard app, whatever, and get both an accurate picture of where the towers broadcasting the stations you need are, and what frequency band they are using. This will help you both pick the right kind of antenna and where to put it. You could also just buy a flat antenna that has good reviews off Amazon, slap it up behind your TV, and hope for the best. It might even work. Just don't be shocked if it doesn't.

They work like poo poo if connected straight into the TV, but if you hook them up to a coax cable and feed it to a window/line-of-sight of a window they work excellent

I did some fuckin' around and getting the Leaf 50 placed high in our apartment solved the problem. I was considering getting some rabbit ears solely for VHF signal.

It was fun watching live ABC via DTVN come in with poo poo resolution, presumably because of their compression hijinks and comparing it to the antenna and getting it much, much more clear. I've heard rumors that a lot of OTT and cable providers just take an antenna signal and compress it for their customers in certain areas.

Those aren't rumors that is exactly what they do, all of them everywhere. Your average channel piped over a bandwidth constrained cable or satellite link is likely going to be compressed to the 5Mbps-10Mbps range, usually mpeg-4/h.264 - and 10 is if you are lucky (or, in the case of some broadcasters like Discovery, they've negotiate minimum bitrates in to their contracts). OTA signals are 19.2Mbps Mpeg-2, though obviously if you have something like Plex or an HDHR re-encoding it you'll get that sent to your TV - though at least there you have a measure of control.

Good post on UHF/VHF

The whole VHF thing is definitely something I've never considered for my antenna, as there is exactly one channel I cannot get, no matter how hard I try. I didn't have any issues getting it at my old apartment which had a pretty much straight unobscured line of sight to the Cincinnati stations. In the new apartment, I have a lot more in the way, but at least I get the Dayton stations too so I'm not missing the CW and CBS.

I've got an old Radio Shack, double bow-tie with reflector (sadly, discontinued like 10 years ago now), perched high atop a bookshelf, in my room pointed at Cincinnati, and fed back through the pre-installed Time Warner cable junction box, it works pretty great.

I have ps vue and just installed a new device (Fire TV 4k) and now I can't rewind or fast forward live tv. I can pause tv but when I try and go backwards (or forwards after a pause), it doesn't do anything and tells me to restart the program. It's like it builds some kind of buffer because it allows me to pause but never lets me travel across that buffer.

Has anyone else had this issue? Did you fix it?

The only time I've seen that when I used PSVue was for live sports. But I just figured "eh, it's sports. they're super weird and specific about their broadcasts"

Have you tried it on a different device? Like phone/tablet/PC?

I've also seen that with live sports on PSVue. After the game completes and changes to a DVR recording the fast-forward / rewind works normally.

Except this isn't live sports. This is every channel. I have 4 different devices in my house that stream ps vue. 2 of them (an original 2014 Fire TV and a 2015 Fire TV 4k) stream Vue just fine and I can forward and backward through shows all day long (within normal limitations like the 4 minute pause buffer or with on demand content with commercials). The other 2 devices (a brand new Fire TV 4k pendant and a sony 930e tv), I can only back/forth through shows if they're in the DVR section.

So it's not just sports and it's not all devices.

Depends on the local franchise (monopoly) and often even the channel,; these days the trend is mpeg-4 simply because they can cram more poo poo in. Switched video (think U-Verse, etc.) was supposed to alleviate this but in practice...well. That said yes mpeg-2 is still widely used around the country still.

I'm guessing the channel is probably Fox which due to its later entry in the broadcast arena (remember that until the late 80's there were really 3 "big" broadcast networks in the US, not 4) went VHF in a lot of markets for a lot of reasons...which worked out ok, more or less, when TV signals were analog. Digital transmissions are less forgiving.

Not always the case today of course, and there are several Fox markets that broadcast in UHF but it is more common than not to find them at the lower VHF end of the spectrum. Whereas in the 90's what is now the CW (used to be two networks, The WB and UPN, Google it) went the other direction for similar reasons and found themselves in a better position when digital OTA became widespread.

I just discovered the Wipeout channel on Pluto TV. It’s exactly what it sounds like: 24/7 of the show Wipeout. So far I’ve only seen a few episodes from the Australian and Canadian versions. Not sure if they have the licensing rights for the US version.

I mean, it’s no MXC, but it still scratches that itch of seeing people volunteer to receive blunt force trauma to the head.

What cracks me up is the IT'S TIME FOR A COMMERCIAL NO MATTER WHAT, cutting off things sometimes mid-sentence. At least when they come back from the ads, they rewind 3 or 4 seconds.

I've recently discovered they have a Wipeout channel for the UK/CA/AUS version of the show. Also a dedicated New Detectives channel.

Eye Candy is pretty unintentionally hilarious. They have a formula and they're going to get there, no matter how ludicrous it is. And it's not actually very titillating, even as attractive as the women are.

I did - it's great - but almost completely superfluous.
Just think of it this way - if you run coax with the Cat6, you can attached your TV directly to the antenna if necessary. For me, it comes in handy when the cable signal the HDHomerun prime goes out and I want to see if weather is bad. It comes up maybe once per year, but I am glad I have it in place when it happens.
