Whether you want HD channels or not, if you are getting a Genie/HR34,or any whole hole compatible set up you need HD boxes. These boxes will not activate if they do not receive the HD signal during the initial setup. I've had D* installed on 5 houses ,and have never met an installer that carries a pole mount set up with him unless it is pre-ordered. Pole mounts take significantly longer and need to be scheduled as such. Like others have stated the installers get charged if it takes them longer than it is supposed to to do an install and they are late for their next appointment. A standard install should take no more than 2 hours tops, whereas a pole mount will likely take at least twice that between setting the pole and running the additional cable.
I join the consensus that this was a LOS issue. I am in Worcester MA, and had the same issue with our initial install 2 years ago. Our neighbors have 100+ year old maple trees that shadow our entire yard. There was an existing 18 round dish on a pole at the back corner of the property which worked fine for SD channels. Because of the neighbors' trees there was no LOS for the 119 from that spot since it is so low in the sky. It took an email to Mike White's office to finally get the install done,but that is another story. What I did before the rescheduled install was go around the yard with Sat Finder and find out approximately where the new pole was going to have to go. I then called DigSafe myself and dug the trench 12 inches deep,and laid out 60 feet of 2" conduit. I know the cable can be direct buried, but since it was going right along some shrubs and flower beds, not to mention we have dogs that like to dig ,I did not want to run the risk of hitting/damaging it in the future .
When the installer got here, I already had a 10 foot length of 2" galvanized pipe along with 4 bags of mortar to set it in. The installer did argue about the cable not needing to be buried a foot down in conduit, but since I had already dug the trench and had the conduit laying there ,he argument was futile .
