The actual work of pointing a dish
I spent a morning in 2019 trying to get a HughesNet Gen5 dish locked on a house in rural Virginia where the mounting wall was concrete block and the line-of-sight satellite happened to pass directly behind an old oak tree. I ended up drilling six anchor points in different spots, shifting the LNB bracket a full quarter turn, and finally getting a lock by angling the mount two inches to the left of where every app told me it should go. That's the kind of thing that doesn't show up in any manual. Here's how the installation actually works when you're doing it yourself. You need a few things before you start, and you need them in the right order. A magnetic compass, a bubble level, a satellite signal meter or a smartphone app like SatBeams, a drill with masonry bits if you're going through concrete, and a wrench set that covers 10mm, 13mm, and 14mm. The LNB is the horn-shaped piece that sticks into the arm, and it's the part that actually catches the signal. You don't buy an LNB unless your old one is cracked or missing. Most dishes come with one pre-installed. The satellite you're targeting matters. In the US, most residential installs use the 119/110/101 stack, which are positioned in a geostationary arc roughly between 101 degrees west and 119 degrees west longitude depending on the provider. Your location on Earth determines the elevation angle and the azimuth. If you're in Florida, your dish points more south. If you're in Montana, it points more south but at a shallower elevation. The numbers change, and there's no universal setting that works everywhere.
I always start with an azimuth reference because that's the direction the dish faces, and getting it wrong means nothing else matters. Point your compass toward true south, not magnetic south. You have to account for magnetic declination in your area. I keep a pocket declination calculator on my phone because this mistake alone costs me about twenty minutes on every job. Once you have the rough azimuth, mark the center of where the pole will sit with a pencil, not a Sharpie. Pencil leaves a guide line you can erase later.
The mount, the pole, and the first real problem
There are two types of mounts: wall mounts and ground poles. Wall mounts are faster but they tie you to the structural integrity of whatever surface you're attaching to. Ground poles give you more flexibility with positioning but they require concrete work or a heavy-duty post driver depending on the soil. I prefer ground poles when the roofline or wall obstructs the southern view by more than fifteen degrees. If your roof overhang blocks the satellite path, a wall mount won't solve that. You need height. Here's something most guides skip: the elevation angle on a standard 18-inch dish for the 110/119/101 arc is usually between 28 and 42 degrees depending on your latitude, but the skew angle of the LNB is what actually trips people up. The LNB isn't mounted straight. It's rotated to match the orbital position of the satellite relative to your location. If you leave the LNB perfectly vertical, your signal drops by 3 to 5 dB. That's enough to lose lock on a marginal satellite or cause constant dropout during rain. I set the skew by looking at the top of the LNB horn and tilting it approximately 20 to 30 degrees toward the eastern side of the arc depending on whether I'm north or south of the satellite's sub-satellite point. A protractor on your phone does this in about thirty seconds. I once had a homeowner insist the dish was misaligned because his TV kept freezing during heavy rain. The real problem was the LNB was loose enough to vibrate, and the sealant around the coax entry point had cracked. Rain water was seeping into the connector and the signal degraded gradually rather than cutting out cleanly. I tightened the LNB clamp, resealed the coax entry with self-fusing silicone tape instead of regular electrical tape, and the freezing stopped. Regular electrical tape falls apart in UV exposure within a few months. Self-fusing silicone fuses to itself and lasts years. This is one of those details that costs you nothing extra and saves a follow-up visit.

Drawing the signal
Connect the signal meter to the LNB output and to the receiver. Turn the receiver on and set it to read the satellite signal strength and quality. The difference between strength and quality matters. Strength tells you the LNB is getting power and the cable isn't completely broken. Quality tells you the dish is actually pointed at the satellite. You can have 100 percent strength and zero quality if the dish is aimed at empty sky. Adjust the azimuth slowly. I move the dish in increments no larger than half a degree at a time once I'm close. That's about a quarter inch of movement at the edge of an 18-inch dish. Go faster than that and you'll overshoot the peak every time. When the quality bar starts climbing, switch to elevation adjustments. Tighten or loosen the elevation bolt while watching the meter. Peak it, then go back to azimuth and fine-tune again. The two adjust each other slightly, so you'll do two or three passes. It usually takes about twelve minutes from the first adjustment to a solid lock if the general direction is already correct. Once you have a lock, tighten the azimuth bolt while holding the dish steady. Then tighten the elevation bolt. Re-check the quality after both are snug. Sometimes tightening the bolts shifts the dish by a fraction of a degree. If quality drops below 80 percent after tightening, you need to re-center and re-tighten more slowly. This is the most common failure point in DIY installs. People think they're done when the meter peaks, but the act of securing the mount can undo the alignment.
The coax and weather sealing
Run the coax from the dish to the receiver. Keep it tucked under the eaves or along a conduit where it won't be exposed to direct sunlight for more than an hour a day. UV degradation on RG6 coax is real and it happens gradually. The outer jacket becomes brittle, moisture gets in, and signal quality declines over eighteen to twenty-four months. I always use weather-rated RG6 with a solid copper conductor and dual foil shielding. Foam-core coax is cheaper and easier to terminate, but it absorbs water if the center pin isn't sealed perfectly, and once water gets into the dielectric, the signal degrades in ways that are hard to diagnose without a time-domain reflectometer. Terminating the F-connector is straightforward if you do it once. Strip exactly half an inch of the outer jacket, fold the braid back, strip another quarter inch of the white dielectric, insert the center conductor so it touches the very tip of the connector body, and crimp. Over-crimping compresses the dielectric and can cause impedance mismatch. Under-crimping leaves the connection loose and signal leaks out. You'll know it's wrong if your quality fluctuates when you wiggle the cable near the connector. Seal the coax entry point into the house with silicone caulk around the punch-through ring. Don't skip this. I've seen birds nest inside the wall cavity through an unsealed coax entry, and the chewed insulation killed the signal for a whole season before anyone figured out what was happening. A two-dollar caulk tube prevents that entirely.
What this method doesn't handle well
A manual compass-and-level installation works fine when you have clear southern exposure and stable mounting material. It falls apart in tight urban environments where the satellite is blocked by buildings, on rooftops where structural anchors won't hold a pole, or when the available satellite arc is narrow because you're far north or far south of the equator. If your line of sight to the 110/119/101 arc is partially obstructed by more than five degrees of vertical obstruction, this approach won't give you reliable results. In those cases, a professional install with a trained technician who has access to a spectrum analyzer and a higher-gain LNB array is the only practical path. There's no workaround for physics. The process takes about forty-five minutes from unpacking the dish to a confirmed lock on a straightforward residential install with good visibility. Setups that require drilling into brick, rerouting coax through an existing wall, or dealing with an unusual obstructions run closer to two hours. Allow an extra hour if you need to cut a new hole through drywall for the coax entry and patch it afterward. Signal quality depends heavily on the quality of the coax runs you make, the tightness of every F-connector, and the precision of your final azimuth and elevation adjustments. Rush any of those three and the dish will perform acceptably for a few weeks before you start seeing dropouts.
