A UHF antenna (need suggestions here) pointed to pull in the most stations North/South.
Something like a DB2e or a DB4e should work fine for the stations to your south. There's really nothing coming from the north, those UHF stations showing on your plot don't exist on the air. The reception pattern for both is broad enough to pick up both originating locations .

Your plot says you don't need and that you should avoid any amplifiers. An amp will only make new problems.

I'm in San Carlos, 92119 (see TV fool link in my post).

Thanks for verification no amp is needed.

The V/UHF combiner is supposed to have 30 dB isolation between bands (if i'm reading the spec sheet correctly).
The two antennas will be aimed about 111 degrees apart which should also improve the isolation.

I'm leaning towards the DB4e.

What type of separation is needed between antennas?

Which antenna should go higher on the mast?

Still on the Fringe. . .

Hey guys:
its been a while since I've been in here, I'm in La Costa, and have a CM 4228 8-bay with a VHF on top of it, and an RCA pre-amp, feeding a Roamio OTA and Mini. Here's my fool:
http://www.tvfool.com/?option=com_wr...dfafd727615668

My reception usually hovers around 50-60%, which is often a tease. I usually have to go on the roof to adjust the antenna between CBS and NBC/Fox, but I "mostly" get the channels I want. Amusingly, the LA channels still come in almost as reliably as the San Diego towers.

However, the inconsistency has been sufficiently annoying that I'm going to force myself to either upgrade my antenna or switch back to cable. I did notice that "wiggling" the cable from the CM to the pre-amp affects the signal, so now I'm wondering if my pre-amp is failing, or the connection is not good. Would also considering upgrading if there is something better out there.

Any suggestions? I have never committing to pointing to the LA stations, since some local programming (such as Charger games) is specific, but would really like to dial in a consistent signal.

thanks for any advice,

Joel

Newbie in Rancho Penasquitos (92129)

Hi Everyone,
As the title states, I'm a newbie to this forum and have recently got rid of cable. I'm currently using Sling TV for ESPN, etc. but would like to pick up some local channels via an antenna.
I live in Rancho Penasquitos (92129) and have my TV Fool link. Unfortunately I don't have the 5 required posts to include the link to it. Guess I'll have to read and provide a few more posts and follow up with a link.

In the meantime, I would appreciate any recommendations or suggestions on what type (brand, model, amplified) of antenna and installation approach others in this area have used with success. I plan to install the antenna myself in the attic but am open to roof mounted since it's a one story house.


Any other advice or links to general info about this topic would also be appreciated.


Thanks in advance for your help!

Finding it a little difficult to search what I am looking for in this thread, so I apologize if this has been covered.

I'm currently using Direct TV and when the weather is bad, the signal can go from bad to nothing as you all know.
What I used to do was piggy-back off my internet and at least get my locals. I found out through trying this a few weeks ago that this is no longer available. Did COX get wise to this or something? It was nice getting those free OTA channels when weather was bad.
I'm in a bad spot to use an antenna and it's spotty at best unless I use a 500ft antenna to clear hills and trees.

Joel, sorry no one else replied, I'll give it a shot.

You are in a difficult spot, all your signals are far away. What happens if you remove the pre-amp from the circuit, does the Roamio receive anything, at all? I ask because it has its own auto-adjusting pre-amp. In my opinion the only reason to use a pre-amp is if you have a really long (100+ ft) cable from the antenna to the tuner.

Your 8-bay CM seems like the best possible UHF antenna. The only other question is if you still have the screen attached, i.e., to make it directional. (The 'screen door' acts as a UHF barrier.)

Also, how are the UHF and VHF tied together, that could be introducing spurious UHF signal.

Hey, thanks for the response, didn't think anyone read this thread anymore. The feed from antenna to Roamio is probably about 80 ft. I do have a signal without the preamp, but it is better with it (I think, if you think it helps, I'll go up and disconnect it, just in case). The screen behind the 8 bay IS attached, I assume that increases the directional strength. . .actually I get almost equal signal strength between LA and SD channels where I am. The last heavy storm we had in Jan, the antenna blew due north, and I had pretty good reception of all LA locals. I am a bit surprised that I can't get stronger signals from ABC/CBS, as Mt. Soledad is not that far. I'm wondering if changing the RCA preamp might help. The UHF and VHF have a combiner, with an FM filter attached.

Either way, I appreciate your time and response ;-)

Joel

If memory serves me correctly, and that isn't a given, Tenga has bought KFMB-8. Does that mean that Channel 8 will launch the Quest network anytime soon, as Tenga is the launch partner?

15.2 - KBPS2
15.3 - Create
15.4 - PBS Kids, however it's been showing colorbars and running the same programing as on 15.2
I checked whether I vented in this thread about KPBS changes, and I haven't, so here it goes: WTF ?

KPBS is the only channel I care about, and since the last year the quality is down the tubes.

KPBS used to have healthy 15 Mbit/s HD subchannel, now they reduced it to 5 Mbit/s. They realized that 1080i at this bitrate would look like total crap, so they switched to 720p as well. It is barely HD. In fact, I would not call it HD at all, it is DVD quality at best.

They added KPBS2, also about 5 Mbit/s "HD" and two SD channels: Create and Kids, both SD, and both interlaced. Have you tried watching low-res cartoons in interlace? Whenever a line is almost horizontal, it flickers like crazy - your TV needs exceptional deinterlacer to cope with it. And there are many high-contrast lines in cartoons. Also, I don't get why kids need 24 hour programming, when are they going to sleep?

On the other hand, I like the content on KPBS2 channel: all these semi-professional docos, and all the different news from BBC, NHK, DW...

I think it would make a lot more sense to combine two HD channels, this will make up to 13 Mbit/s, which will produce quite nice 720p. This channel would have everything main KPBS channel has sans kiddie stuff. Considering inordinate amount of children programming on both the main channel and on the KPBS Kids, this would allow combining all the different world news programs as well as docos on the main HD channel.

The kiddie stuff will be on KPBS Kids only, but switch it to progressive, I believe ATSC spec allows this.

And another SD channel will have its low-grade Create stuff: home improvement, knitting, cooking, this sort of things.

This is the lineup I would like to see:

KPBS-HD (12 Mbit/s 720p60): docos, news, interviews, quality mini-series (Downton Abbey is not the best candidate). Also, drop the cheap and stupid Antique Roadshow.

Create (3.5 Mbit/s widescreen 480p60): home improvement, etc.

KPBS Kids (3.5 Mbit/s widescreen 480p60): children programming, they should not watch much TV anyway.

KPBS should not think they have so much great programming they need four subchannels - they do not. A lot of cruft that can be removed by switching to three subchannels, this will make for more meaty programming.

I only wish they read this thread. But seriously, are there limits to greed and stupidity? How can they call 5 Mbit/s MPEG-2 stream HD with straight face?

JVC feels that 720p will look good enough at 9 Mbit/s. KPBS broadcasts 5.5 Mbit/s. Seriously?



This is an interesting remark from the JVC's blog linked above:

Quote:
The Disney-ABC Television Group launched its (sub-channel-based) Live Well HD Network in April 2009 and is by now featured on all of ABC’s ten O&O stations in HD, plus on numerous affiliate stations in SD. The “HD” was removed from the network branding after affiliate stations were allowed to carry the Live Well channel only in SD. Sources reported earlier that WABC-TV in New York divided up the 19 Mbps payload bitrate to the 3-channel multicast as follows:

Primary HD for ABC TV Network (7.1) - 10 Mbps
Live Well Network HD Sub-channel (7.2) - 5 Mbps
Live Well Network SD Sub-channel (7.3) - 3 Mbps

This breakdown is interesting, and confirms that the progressive 720p60 can produce “in-home OTA broadcast quality” in HD at 10 Mbps MPEG-2 compression. Presumably, all of ABC’s O&O stations use substantially the same bitrate assignment. The Author resides in Los Angeles and often watches KABC-TV (7.1), including OTA although a Time Warner subscriber. The Live Well HD channel (OTA KABC-TV 7.2) is reported also to be a p60 (rather than p30). The Author is surprised by the good HD presentation quality at 5 Mbps OTA (but remember that the programming is not fast-moving sports), quite acceptable for home viewers as a secondary HD program feed.
Right, Mr. Nordahl, "quite acceptable for home viewers as a secondary HD program feed" meaning "crap that proles should be happy with because the network wanted more ads". Then the same networks will be claiming that HD is not good enough, that UHD over ATSC-3 is the way to go. And you will need a new receiver. And then they will create a dozen subchannels in the ATSC-3 pipe and flood you with targeted ads.

The golden age of HD is over, folks.

How about squeezing THREE (alleged) HD channels on ONE stream? WEEK up in Peoria, IL is doing just that:
25.1 NBC 1080i
25.2 ABC 720p
25.3 CW 720p

WGEM-10 Quincy, IL carbon copy as above, except instead of ABC it's FOX

Bad enough? Let's ALSO throw a 4th SD sub on for good measure in Terre Haute, IN on WTHI:
10.1: CBS (1080i)
10.2: Fox (720p)
10.3: CW (720p)
10.4: Ion (480i)

This is just what's going in my immediate area; there's others either already like these, or going to happen.
Will probably be getting worse, depending on what kind of re-packing is going on in your area...yep, HD quality (at least OTA in many areas) is gone...

Not just the repack - station groups are quickly bulking up on subchannels in prep for ATSC 3. They will be able to carry a lot more subchannels in HD and SD - similar to the way DVB is now in Europe. So they're getting the agreements in place, and in a lot of cases buying/consolidating the programming...so they're putting it on the air now as a result.

Of course - it will get really messy when they start to rollout ATSC 3 as the stations in a market will merge the ATSC 1 channels onto a couple of station frequencies (don't be surprised to find 5-9 stations sharing a single ATSC 1 frequency) while the rest of the channels in the market launch the ATSC 3 signals. If you want to keep real HD - you'll have to be an early adopter of an ATSC 3 tuner.

We'll all watch Phoenix later this year and that will be a sign of what's to come for the rest of us. :-)

My parents live in Rancho Penasquitos (92129), on the side of Black Mountain, and they're fed up with Spectrum.
They have line-of-sight to Soledad, but Mt. San Miguel is on the other side of Black Mountain. An indoor antenna gets the Soledad stations (and sometimes LA), but nothing from San Miguel.

Would an attic or outdoor antenna reliably receive the San Miguel channels?
Also, can anyone recommend a local antenna installer?

Thanks for any help!

Well not to derail your San Diego posts, but I spoke too soon (on Quincy having 3 HD on 1 stream)...WGEM-10 recently added another HD sub-channel (MeTV) - so they are now running FOUR, HD, channels on one stream!!!

Broadcasters never cared for HD, they did not want it, they just wanted to keep the spectrum. Now, when many of them gave their extra spectrum away, they realized that they may need it for more subchannels, so they squeeze the hell out of what they have. I guess they figured that only 65+ olds watch live TV nowadays, and these folks have bad vision anyway.

So, after ruining the video quality, KPBS runs more and more ads, and has a nerve to keep asking for donations. Public TV goes to the tatters, and commercial channels have never been good to begin with. I am on Netflix these days (paying to Reed Hastings despite that he is a hater of public schools).

P.S. A couple of weeks ago KBPS ran for several hours with video seemingly lacking red component: several programs were green-blue. Eh.

Anybody got XHTJB-TDT, virtual 11-1 in Tijuana ? It's the IPN affiliate.
I haven't seen it on air for about a week.
I've read that they would be switching from RF 46 to RF 15 but I haven't seen any signal on RF 15.

Instead of dropping one HD channel, keeping incessant children programming on KPBS Kids, and increasing bitrate for their main HD channel, KPBS did a much simpler thing: they changed their logo. Among other reasons for the change they say the old logo "was not digital-friendly for streaming and online content platforms". I take it, it had too many lines and colors, so showed significant compression artifacts on their overcompressed feed.

These hacks dare calling their ware HD television.

Local NBC station might be thinking of moving down to RF 17 from RF 40. Generally the lower the frequency the greater the coverage.

Yesterday I saw KGTV 10 also transmitting its 4 channels on RF 20 . I don't know what to make of that.

Numerous station will be moving channels in March as part of the FCC repack.

Not sure what KGTV is doing...but both KGTV (10) and KFMB (8) applied to the FCC to increase their transmission power in Nov 2017. Unfortunately, I don't think the FCC is going to do anything with that until after the repack in this market.

Maybe they finally realize that VHF has no place in southern California - as that signal cannot penetrate a stucco wall - which covers a lot of homes here!

San Diego - OTA

I'm having issues with HDTV reception in Northern San Diego County.

TVFool report: tvfool DOT com/?option=com_wrapper&Itemid=29&q=id%3d903872fc264ff 2

Current set up is attic mounted Clearstream C5 for VHF and Clearstream 2 for UHF going to an RCA TVPREAMP1R combiner/preamp.

UHF channels come in great all the time, however VHF channels 8 and 10 only come in during the day. At night or even during rain, they die completely. What's the best thing to do in this situation? Better VHF antenna? Better preamp? The signal strength is 100% on those channels when they work using the pre amp, and around 70% without the pre amp when they work.

Thanks for any advice.
