Good to Go! What a big dummy (I am)! Always watchful of the distant treeline to make sure they don't interfere with the birds I need, when I re-pointed for Galaxy 19 I didn't notice a limb encroaching from a near tree that was ABOVE my dish. I thought it was well above my line-of-sight, but a...

I did the "string thing" a couple of years ago on my dish and had about 1/2" gap where the strings crossed. I flexed the dish (without removing it from the pole) until the strings just kissed. I had checked my Father-in-Law's, before I mounted it, on a concrete floor (and yes I rotated the...

I've always regretted not making it to a Saturn V launch. I've seen two shuttle launches and hope to make it back down for one of the remaining 3.

I peaked on 11842, because that was the primary target. I played with the skew, which has a fairly slow peaking response. Don't get me wrong, I ended up with ~200 watchable TV channels on Galaxy 19, but the margin is so very low compared to AMC4. A little rain and I've got nothing.

I have re-pointed two different Ku systems from 101° to 97° and am having a tough time getting decent signal levels on Galaxy 19. Both systems are using 90cm dishes and Mercury II receivers with a single LNB. I bought a new LNB for my dish to see if if made any difference. Nope. After much...

Only been doing the FTA thing for 3-years. Don't remember the first channel I saw, but the first one I watched was Planeta on AMC4. Watched the Bulgarian music videos for a couple of hours in amazement. Sadly, the channel is encrypted now.

The same thing has been said several different ways (all correct!), but mathematically, linear and circular polarizations are not orthogonal. There is only a 3-dB separation between the two methods. The isolation we need between cross-polarizations isn't there to permit simultaneous use...

If you don't want to take your dish off the mount and remove the LNB arm, you can also do the "string test". Tape two taut strings across the face of your dish. One running top to bottom and the other running side to side. The strings should just barely touch in the middle. If there is a...

Thanks Iceberg for the info! My family has missed GMT since they left Sky Angel. I have them scanned in on AMC4 on two of my receivers. Now I've got to talk a couple of relatives through setting up their receivers over the telephone.

A block diagram and/or a few more details would help... This monster cable. Is it a coaxial cable for RF or is it Audio/Video Cable? If your using a splitter, it sounds like your dealing with RF? Is it just a two-way splitter? Are all the ports properly terminated? If you're dealing...

A few years back, I installed my DTV dish to a pressure treated 4x4 post. I had to repoint my dish about every 3 months for a couple of years until that post finally stabilized, after many additional coats of water proofing. Go with steel! I put my WildBlue satellite dish (more finicky than...

Actually, the US Guvmint uses the term magnetic declination. http://www.ngdc.noaa.gov/seg/geomag/declination.shtml Magnetic deviation is the error in a compass reading due to some local perturbation in the earth's magnetic field due to such things as a large amount of iron ore in the ground...

Thanks Iceberg for the info. Now I have to figure out why I couldn't see the NASA channel or Skyangel or any of the radio stations @ 119° ...?

I was playing with some FTA toys that santa brought me and was trying to add a 2nd dish to my Twinhan 102G card. I had a virgin 18" dish/lnb for DTV from the old days when it was cheaper to buy a complete system than just a receiver. Wanting to do "something" with that dish, I tried to aim it...

It brought a good laugh from everyone when I opened one package and exclaimed, "Wow, a quad circular and linearly polarized low noise block amplifier! Honey, how did you know?"

Merry Christmas to all! ____________________ Santa said he wouldn't be coming to see you this year. He said you would know why. :D

The signal-to-noise ratio coming out of the LNB is the best it's ever going to be. No in-line amplifier, no matter how well designed, can ever improve that. It can only add noise. However, for long cable runs (+150 ft) or if you get stuck using RG-59 or low-grade RG6 pre-installed in your...

No. But thinking about it. I have a fixed 90cm on AMC4. So, if I replaced the LNB with the Invacom Quad, I could feed my DirecTV receiver with the DBS port? I could retire my DirecTV dish? The larger FTA dish would improve my rain fade margin? Are there any disadvantages to this...

Been a ham for 38 years. Worked 48 states on the Russian satellites ~15 years ago. (Only missing SD and MS because of lack of activity). Just got into FTA a few months ago, but having fun with it. :)

FWIW, I am a FTA newbie also, and tried to find IA5 a few weeks ago. I thought it *very* difficult to find with a 90cm dish and a Lifetime Ultra receiver. On the other hand, I could find AMC4 in 2-3 minutes. Finally, by indexing from AMC4 (moving a slightly to the left and a little higher) I...

I used pressure treated 4x4 for DirecTV and it was unsatisfactory. I had to realign the dish every 3-4 months for about 2-years when the post would twist one way when it was hot and dry and twist another when it was cold and wet. Finally after time and a gallon or so of Thompson's...

FWIW, Wildblue (my internet provider) installation standards require a minimum hole depth of 30-inches and 120-lbs of concrete for their 26"x28" dish when pole mounted.

I have a fixed dish on AMC4 mounted right next to the house, but am considering adding another dish with a motor. To get the angular coverage I want I will need to run ~125' of coax. If flooded cable is used is it OK to direct bury the cable or should it still be run in conduit?

An estimate for dish beamwidth is Bw = 21900 / (F * D) Where F is the frequency in MHz and D is the diameter in Meters. So, for your 1.2M dish at 4000 MHz, the beamwidth would be about 4.6 degrees. Note that this formula calculates about 1.8 degrees for your 10-foot dish. If you are using...
