D* Offers a triple SWM ODU to catch just the 99/101/103 birds. OK 3 birds is all you need when your Locals are on Ka (mine are)
So a question...... If you're working with a legacy AU9 dish can you get away with running only 3 coax downleads to your SWM-8?
I've been told that I've got to have 4, but I'd like another opinion and maybe an explanation why.
Thanks!

Yes. -and doing it ourselves- but don't roll your eyes as we did our own 24 channel Blonder-Tongue head-end and distribution several years ago with great success. Tight system, spectrally clean, BIDA 450-30 trunk amps and all unused ports terminated. This will not be our first rodeo.
My building is unique (aren't they all?). Seriously, it's a 9-story "shoebox" 640 ft long and 85' wide. There are 40 (total) wiring closets, 10 in each of 4 vertical risers (including the basement). I'd like to cable the whole thing out (including passives) but only heat up the front end and only as much trunk as necessary to reach the (so far) first and only client via riser #2 down on the 3rd floor.
MFH2 right now is overkill, but I can see far enough ahead to know that's where I'd like to be at the end of the day.
I can go cheap & dirty with just a SWM ODU and a single run of RG11 plenum to the 1 lonely client and forget all about building a backbone, but that's setting a dangerous precedent because as we all know one client soon leads to two and so on and I'd really prefer not to end up with 50 dishes on the roof 5 years from now. Right now there's just under 100 NTSC televisions on "our" cable system and we've just had our first request for HD to a client who is installing three 65" displays in the master control center of a major energy company (my employer).
I've seen diagrams of several MFH2 systems (Sonora based) and that is unarguably the way to do it, (not necessarily w/Sonora) but regardless whose electronics we use that's spending cubic dollars when today there's only a single prospective end user who for the near term at least will have only 3 tuners. If I'm going to do something like an MDU, I've got to be able to eat that elephant one bite at a time from the standpoint of rolling out the electronics and paying for it all. I have the cable (RG11/Quad/Plenum) & connectors to lay-in that much of it now and taps are cheap enough that they won't break me to do that too. I figure on a single SWM-8 in every other wiring closet (staggered floors, 2nd, 4th, 6th and 8th)
I've got to work up a viable design where I can walk-in the electronics to the system strictly on a 'demand' basis. I have all my loss and slope numbers for the cable lengths. The horizontal run is what's eating my lunch because even with RG11 I have one leg of it (between the #2 and #3 risers) that on paper has 10 db of slope in 15 db of attenuation. All the amps I see have only 5 db slope compensation max, suggesting I'm going to have to put equalizers in or run more amps with lower individual gain. I want to keep the trunk as flat as I can without spending a fortune to do it. I didn't see any designs that addressed this hurdle.
We are the only tenant in the building; 1400 employees, 550,000 sq. feet of office space. (12+ acres under roof). We currently have two D* business accounts and 33 GAEBO IRDs (24 in the head-end with B/T modulators & combiners) plus 9 in dedicated applications around the building (so we're reasonably familiar with the amplification requirements of pushing L-band signals thither and yon down long runs of RG11 and winding up with a presentable signal at the other end.. I was simply choking a bit on the concept of quadrupling the L-band backbone and curious as to where we could trim unnecessary expenses. Thoughts welcome.

4 Slimlines would need 4 PI/PL units plus 4 amplifiers
2 Slimlines would need 2 PI/PL units, 2 HFS splitters, plus 2 amps.
Net gain = equip. savings. Cabling is the same. Net signal loss is 11 db with 4.5 db of slope. I can buy 2 HFS splitters & 2 higher output slope-compensated amps for less than I can 2 more Slimlines, PI/PL's, and 2 additional amps. The problem was the slope. 2 head-ends solves it for less than I'd have spent on 1200 more feet of coax & electronics to try & feed it all from 1.
Sounds like you've done this before. Any recommendations on brand of electronics? (or anything to avoid?)
What's a good source for 2150 Mhz-rated directional couplers/taps? (range of 3 to 20 db) One vendor (!) suggested to use all 2X splitters and add pads on my inputs. Clever, but overlooks the high thru-loss (50%) of the splitter. Obviously he had splitters & pads in stock but didn't have taps... He also didn't understand what slope attenuation was. To him loss was loss. I'll refrain from mentioning names (Lum-n-Abner's Supply House, Bait & Boats Rented)
You make a good point Bob. Unfortunately, existing MPOE penetrations are nearest risers #2 and #3, so 4 slimlines vs 2 would not improve signals more than 3.5 db (splitter loss) in risers #1 and #4 compared to using only 2 with branch feeders (The amount of cable would be approx. the same. Either 2X as much downlead or 2X as much for the branch trunks). I can compensate for the slope in 150' of RG11.

HERE TO HELP YOU!
Cutting Edge
Sometimes a thread gets so many posts in it that is can cause issues for the server so that why today we introduce The Song Name Game Part 3!
So let the game continue!
The last song was added by Bobby who posted...
One Meat Ball - Andrews Sisters
CONTINUE ON AND HAVE FUN! WELCOME HOME TO SATELLITEGUYS.US!
Here are the original rules for the game as posted by WebbyDude back in 2006. http://www.satelliteguys.us/threads/68645-Song-Name-Game
Just name a song title and the band who performed it. The next person does the same thing, but needs to list a song title or band name which includes a word from the previous entry. Pick songs from any genre.
Example:
Long Live Rock and Roll -- Rainbow
Rainbow in the Dark -- Dio
Another example:
Ride the Lightning -- Metallica
Lightning Strikes -- Ozzy Osbourne
Get it?
An additional note: we all know that song titles, sometimes, use profane words. Because this is a family friendly website it is advised that you clean up that title up a bit. This is accomplished by using something like sh!t instead of the real word. Thanks....

I remember this in the news too...
www.nbcnews.com
$14,000 spent on rented rotary phone
A widow rented a rotary dial telephone for 42 years, paying what her family calculates as more than $14,000 for a now- outdated phone.
www.nbcnews.com
That is a misnomer. In the old days you subscribed to telephone service. That included the telephone line and one telephone. An extension cost $1 a month extra. So that $14,000 over 42 years was for the service not the leased telephone. There is no way they paid $28 a month for 42 years for a leased telephone.I remember this in the news too...

I haven't posted in almost 17 years. Over the air, sat, offline, anything-but-the-internet is still one of my avid pursuits. Been playing with offline tv viewing and offline web browsing. I have great appreciations for this site still being here. It's so hard to find public communities that haven't sold out to social media company.

Hello folks, well my luck ran out last week with a nasty thunderstorm and after 39 years here, finally took a hit. Now, the FTA receivers I had for some years worked great until now. Recently picked up a fairly cheap receiver, online, KOQIT and seems to be good, but for the life of me, I cannot get the HDMI output to work with 3 of my Samsung monitors. I can hook it up to my Samsung TV and its HDMI input and it works fine. The 2 receivers I lost also worked fine with them, so am I going crazy? anyone have come across this or have any suggestions? And, since this is a somewhat cheap unit but works, what is everyone out there using for receivers these days? without breaking the bank? I enjoy watching FTA TV, so I will invest more if needed, what is a really good, detailed unit these days. I'm so use to watching a few of them HD channels. Right now I'm down to composite hookups, yuck! Any help or info would be greatly appreciated. Thanks Frank

Take the cover off, show me pics of the board of the bad one and also the bottom of the board. I'm an old hardware electronics tech plus a satellite dealer; I fixed a lot of FTA and regular receivers. I may be able to fix it for you. And yes, they got hit by lightning; it's best to email me the pics at diamondsatellite@snet.net or call me at 203-232-8888. I give you a 50-50 chance of fixing it; I do have spare parts. my phone is a fliptop phoneHello folks, well my luck ran out last week with a nasty thunderstorm and after 39 years here, finally took a hit.
