    I think you'll have no problems getting the 16 and 32 feeds once this is dialed in. Especially since many of the satellites have more power in the southeast.

    This is the kind of power output I am looking for. I think 5 amps will drive the actuator I have, but would not mind having a controller that is rated at 10 amps like this one.

    PHYSICAL
    Size:

    Input Power:
    115/230 VAC, 50/60 Hz., 40 W
    OPERATIONAL OVERVIEW
    The RC1500 was designed to provide years of reliable operation through the use of a heavy duty solid-state drive network couple
    d with a novel
    microcontroller-based fault monitoring system. The 10 amp rated drive output capability is adequate for either moving feed tra
    ckers or full-size
    linear actuators and the Adapti-Drive digital servo speed control optimizes antenna movement for today's demanding Ku-band appl
    ications.
    Additional features like an RS-422 communications port for PC control and a very user-friendly, menu scheme make the RC1500 a u
    nique and
    highly adaptable piece of equipment. Overall, the RC1500 is well equipped to handle the demanding requirements for cost sensiti
    ve domestic
    and optionally international inclined-orbit satellite tracking.

    Another option would be to purchase a power supply and add it to an existing positioner such as a VBox.

    When upgrading to a bigger dish size, always try to at least double your surface area or else you will not see much gain or signal increase, providing the replacement dish and the original dish are of equal performance. A crude way of doing this is to use a circle calculator. Half the distance across is the radius for a circle.

    My 7.5 foot dish would have a surface area of about 45.36, while the 12 footer will have about 113.1 in surface area. I should have noticeable gains in signal strength since the area is doubled.

    In the C band world, a 3.7 meter dish is about the equivalent of a 1.2 meter Ku dsh in respect to gain and rejecting signals from nearby satellites.

    A 3.7 meter dish will give me about 41 dbi of gain at 3.6 GHz, and will cut the signal in half (reduce by 3db) at 1.52 degrees.
    A 1.2 meter dish will give me about 41 dbi of gain at 11.7GHz, and will cut the signal in half (reduce by 3db) at 1.44 degrees.

    The above information is rough estimates, but it gives you something to go by when upgrading to a bigger dish.

    I guess it is time to quit talking about it and start digging the hole.

    Looks like I found a nice long pipe to put in the hole.

    I hope to have the hole finished tomorrow, but it will take as long as it takes to get the depth I want.
    The digger handles should be even with or below the ground. We will see if i can get it that deep.

    My goal on concrete is at least 15 bags. Each bag will weigh 40 pounds or 18 Kg. I am digging in slate rock and clay. The hole depth and amount of concrete I need may not be the same for other parts of the world.

    I think it is 13' 5", and schedule 80. It will have to be cut because I am not going to stand the dish that high. I am going to try and keep the dish as low to the ground as possible...within reason.
