Starlink under tall pines and firs: clearing, pole or tower?
Height helps less than distance under very tall conifers. Run the angle math on each spot before you pay anyone to cut, dig or build.
$100First Starlink? The pre-order checklist and our referral link- Under trees much taller than the house, moving the dish away from the trees lowers the treetops in its sky faster than raising it.
- By our geometry, treetops 100 ft above the dish need to stand about 143 ft away to sit at 35° and about 275 ft away to sit at 20°.
- Starlink's 20° figure is its guidance for business installs; it publishes no clearance or height rule for homes.
- Starlink's installers can't do pole mounts, so poles and towers are yours to arrange, permit and maintain.
Under very tall evergreens a pole rarely clears the treetops. What usually works is distance: a spot in a clearing or farther from the trees, or at a few homes a professionally built tower. The angle math tells you which before you spend anything.
A Hacker News commenter put the problem bluntly in July 2026: where they live, the trees are so tall that Starlink isn’t an option at many homes (Hacker News). That’s true at some houses. At others, the spot that works is 100 ft out in the yard.
Why a taller pole helps less than you’d think under 100 ft trees
Raising the dish lowers a treetop in its sky. Moving away lowers it faster when the trees are far taller than anything you could build.
Our geometry, for one 100 ft Douglas fir and a dish 60 ft from it:
| Dish setup | Treetop angle seen from the dish |
|---|---|
| On the ground (about 2 ft up), 60 ft from the tree | about 59° |
| On a 20 ft pole, 60 ft from the tree | about 53° |
| On a 30 ft pole, 60 ft from the tree | about 49° |
| On the ground, 140 ft from the tree | about 35° |
| On the ground, 270 ft from the tree | about 20° |
A 30 ft pole is real work and money, and it still leaves that tree near 50°. Moving the dish 80 ft farther out does more than any pole you’d set yourself. To bring the same treetop down to 35° without moving, the dish would have to sit about 58 ft up. That’s a tower, not a pole.
The two lines this site uses: 20° is the clear-sky line in Starlink’s guidance for business installs, which asks for open sky from about 20° above the horizon all the way around. 35° is our reading of where the edge of the 110° field of view Starlink lists for its home dishes would sit if the dish pointed straight up. Starlink publishes no clearance or height rule for home installs, so treat both as our geometry.
How big a clearing the dish needs
The table gives the distance from the dish to the nearest trees, for treetops at a given height above the dish. Our geometry: distance = height above the dish ÷ tan(angle).
| Treetops above the dish | For 35° | For 30° | For 25° | For 20° |
|---|---|---|---|---|
| 40 ft | 57 ft | 69 ft | 86 ft | 110 ft |
| 60 ft | 86 ft | 104 ft | 129 ft | 165 ft |
| 80 ft | 114 ft | 139 ft | 172 ft | 220 ft |
| 100 ft | 143 ft | 173 ft | 214 ft | 275 ft |
| 120 ft | 171 ft | 208 ft | 257 ft | 330 ft |
“Above the dish” means tree height minus dish height. A dish on a 10 ft wall under 90 ft firs uses the 80 ft row.
If trees ring the spot, the clearing has to be twice that distance across. Treetops 100 ft above the dish need to stand about 143 ft away on every side to stay under 35°, a clearing about 286 ft across, or roughly 1.5 acres. Keeping them under 20° takes a clearing about 550 ft across, more than 5 acres.
You may not need the whole circle. Starlink says the dish does best with open sky and can often get by with part of it. The dish is aimed one way with the app, so its view reaches lower on one side, and Starlink names no compass direction that matters more for current home dishes. Don’t write off one side of the clearing. The field of view page explains why.
Our reading: the nearer your worst trees are to the 20° column, the fewer dropouts you should expect. Between 20° and 35° is borderline. Past 35° on several sides, expect regular interruptions.
Moving the dish out: cable length and the yard spot
Distance is limited by the Starlink cable, measured along the route it actually takes (up the pole, across the yard and through the wall), so check the lengths Starlink sells and its no-splice rule in the cable guide before you pick a spot.
Out in the yard, the dish needs a pole or a ground mount. Starlink’s Standard Pipe Adapter fits metal pipe 1.25 to 2.5 in across, and Starlink’s installers can’t do pole mounts. The pole guide covers height, footing and guying. In an open clearing, a ground mount may be enough.
Towers: when they make sense and who builds them
A tower makes sense in a narrow case: no clearing within cable reach, trees you can’t or won’t cut, and a height you can actually reach. Starlink’s own fix steps say you can use a third-party tower or pole, and its installers won’t build either.
- Who builds them. Contractors who put up antenna and radio towers, or a capable fabricator. One TractorByNet member describes a welded mast of about 50 ft (TractorByNet).
- What drives the price. Height, the footing, guy wires or a self-supporting design, site access and any permit. Starlink publishes no tower guidance, and we have no dated price to print. Get written quotes.
- Permits. Starlink’s terms make you responsible for building codes, zoning and permits, and for their fees. The FCC’s OTARD rule covers a mast that supports a covered antenna, but rules with a clearly defined safety purpose can still apply. General information, not legal advice: see the OTARD guide.
- Safety. Starlink’s terms say that if you can’t install safely, don’t, and get professional help. Keep any tower well clear of power lines.
- Lightning. A tall metal tower is the high point on the lot. Starlink says its kit meets US National Electrical Code grounding requirements and that an external lightning protection system may reduce the risk where lightning is common. Ask a licensed electrician.
Regional notes
- Pacific Northwest (WA, OR, northern CA). Douglas fir, western red cedar and hemlock, evergreen all year and often the tallest trees on this list. Look for openings you already have: a pasture, the driveway, the far side of the lot.
- Southeast (GA, the Carolinas, AL, MS, east TX, north FL). Loblolly and longleaf pines mixed with hardwoods; live oaks keep their leaves. Leafy hardwoods change the answer between winter and summer: see winter scans and summer leaves.
- Appalachia (WV, KY, TN, western NC). Hardwoods on steep slopes. Trees on a ridge add to the ridge’s own height, so check the terrain guide too.
- Mountain West (CO, MT, ID, WY). Dense lodgepole pine and spruce stands, with aspen that leafs out. Canyon walls add terrain on top of the trees.
When to stop: signs no spot will work
Wait, and don’t order yet, if any of these describes your place:
- Every spot the longest Starlink cable can reach shows treetops above about 35° on two or more sides.
- The clearing you’d need is bigger than you can legally or affordably cut, or the trees aren’t yours to cut.
- The only fix is a tower nobody has priced, or one you can’t maintain and take down safely.
- The Starlink app scan from the best reachable spot still shows large blocked areas.
Measure each candidate spot with the sky angle calculator, scan the best one with the app, and run the fit check again after anything changes: a tree comes down, a clearing opens or a tower gets quoted.
Questions this page answers
How big a clearing does Starlink need?
It depends on how far the treetops rise above the dish. By our geometry, trees 60 ft above the dish need to stand about 86 ft away to sit at 35° and about 165 ft away to sit at 20°, the clear-sky line in Starlink's business install guidance.
Will a 20 ft pole get Starlink above 100 ft trees?
No. When the trees are close, a 20 ft pole lowers the treetops in the dish's sky by only a few degrees. Under very tall evergreens, distance from the trees usually does more than height.
Can Starlink's installer put up a pole or tower?
No. Starlink says pole-mount installations aren't included and its installers can't do them. Its fix steps mention third-party towers and poles, so that work is yours to arrange.
How far from the house can the dish go?
As far as Starlink's cable reaches along the route you'd actually run it, without splices. This site's cable guide lists the lengths Starlink sells.
Do I need a permit for a Starlink tower?
Possibly. Starlink's terms make you responsible for building codes, zoning and permits and their fees, and some towns require a permit for satellite antennas or tall masts. Ask your building department before you dig. General information, not legal advice.
