If you are using the DTV contractor rate many charge as your foundation for thinking $130 is fine for a WildBlue install then you need to learn a few things about business.
Your business should earn no less than $50 an hour for your installation time. This includes travel. The ONLY way you can expand your business is to reach a point where you can hire other installers. If you hire employees, they will cost you at least $25/hour after wages, taxes, ect... Your business must charge TWICE that amount for labor.
At a minimum, your should allocate 3 hours per install. You also need to consider any warranty work, that must be paid to your installer (even if it just you) from the installation fee. 3x$50=$150. Add in materials, vehicle expense, and other expenses and you reach $180-$200, easily.
Wildblue selected the $179 installation rate because they figured this out and knew dealers who used in-house employees would come to the same conclusion. If a dealer has an employee, the dealer assumes 100% of the risk. If there is a warranty service call required, the dealer pays the employee, the gas ect... The dealer pays all materials and assumes all risk.
If a dealer does not generate a steady work flow to justify hiring an employee, then they can hire a contractor. The contractor assumes the role of the dealer who hired the employee. The contractor assumes the risk and expense, and in turn should receive at least the same installation fee the dealer receives.
Side note: IMO, the contractor should be paid even more. I charge $120 + a trip fee (paid by the customer, ranging from $5 to $50) for a DISH or DTV single rx install. The dealer only receives $100 for the install.
Any dealer who has ZERO expense or risk towards the installation and keeps ANY portion of the installation fee for themselves is NOT a dealer I can respect. On the other hand, if they can find a sucker who will work for less, can you really blame them?
There are situations where accepting less than $179 would make sense. I have a deal with my dealers that if they generate decent volume in a month, I give a discount. If I can schedule three installs a day in the same area, they get a 5% discount.
If they generate over 10 installs in a month, they get another 5%, 15 installs a 7% discount, and 20 installs a 10% discount. So if a wildblue dealer had a contract with me, they can earn a 15% discount with decent volume and if I can schedule efficiently. That brings the effective WB rate to $156. But that is OK, because I did not have to drive very far from one install to the next. With gas prices, it works out just fine for me.
I use this same approach for DISH network and DTV installs.
