The installer is comming out on Sunday. Do they have a chimney mount option or is this something I can pick up at a place like Radio shack?
He may have one but I wouldn't count on it.
Will he be able to get a good ground with the dish on the chimney?
Is it a brick chimney? Yes use TAPCON screws right into the brick using the standard mounting foot. ZOf course he will need a hammer drill to drill with.
Bob, Like I said earlier, I've had two chimney mounts with Tapcon screws for 11 years and I have had zero issues with it in all that time. To add to that I also have a 2 Radio Shack strap type chimney mounts that hold up my Channel Master 4228 antenna. We get wind here all the time, like daily, because we are just 30 miles from the Pacific Ocean. In those years we have had many episodes of gale force wind as well. Much ado about nothing......
thats all well and good BUT a bad cap nearly killed me and my grandma years ago. a friend who happended to be a volunteer fireman stopped and recognized the symptoms, saving our life.
now ours wasnt caused by a dish but they definetely vibrate in the wind, and that can cause cracking........
and how far up is your dish the nearer the top the better the chance of troubles.
let alone dish getting contaminated by chinmey exhaust....... espically wood fires
so relax if you want but a roofer i know reported lots of chimneys get rebuilt after being dished..............
this probably explains why E doesnt do chimney mounts.
as long as anyone can get line of site for the dish theres no advantage to extra height, it just makes service harder, and snow removal a pain.
after all the satellite is at 22,300 miles how much does 30 feet help?
I believe some have posted here that Dish no longer allows chimney mounts.
You might also consider an eave mount, if you don't want roof penetrations.
OK, I'll pass on the chimney mount. My chimney is very old. Just an idea...I guess a bad one.
It sounds like you used the drill into the bricks or masonry type mount. The strap types spread the stress all around the chimney where as drilling all the way thru the brick gives the chance for water to ingress into the hole and crack when it freezes. I put up a chimney mount for my brother 7 yrs ago using the straps and he recently switched to E* from D* and checked the chimney and was showing no problems of hurting the mortar.
inside of chimney is ceramic liner, you dont want to drill into that.
you dont understand the CHIMNEY CAP is masonary cement around the liner where it protrudes thru the bricks.
If the mortar cracks there on the TOP the water can get trapped between the liner and bricks expand when it freezes, cracking the liner which pieces fall down the flue so exhaust gasses cant get out and backup in your home.
its like car exhaust it KILLS!
the trouble isnt drilling into chimney.......
its the dish vibrating in wind, causing cracking
Then don't drill into it use the strap type mount and there will be no holes for water to enter the chimney. I'm not the one that advocates drilling into the chimney. You need to address that with the person that says they use the Tapcon screws. I never have used them and don't even know for sure what they are. Strap type mounts shouldn't cause cracking of the mortar unless it is already weak, crumbling, and needs to be replaced. Please don't confuse what I have said with those that are talking about drilling into the brickwork.
the issue isnt holes! AT ALL!
Its the VIBRATION!!
Vibrating dish, dish acts like a wing airfoli, makes chimney vibrate.
vibration causes masonary to crack, and the cap.... cement surrounding liner, cracks.......
water enters between liner and bricks. freezes, breaks liner which falls into flue and clogs it, exhaust gasses back up into house. can kill.
the CO2 actually replaces the oxygen in your blood stream, no oxygen you die.
our symptoms the day it occured.
bad headache, weak in knees, nausea vomiting and poor thinking
It's not a bad of a problem with the strap attachment due to the fact that the straps can flex a bit. I herd the issue that you you were talking about with the vibration but not sure that it is as big of a problem with the type of mount I'm talking about. As I said I have installed one on bro's house and it has been there something like 7 yrs now and has not cause any problems. Now attaching by drilling directly into the masonry would have more problems with the viberation since it will try to break the bricks loose from the chimney as these direct bolted units have no give in the mount what so ever.
