power antenna question
I read the FAQ on how to make the power antenna work. But what is missing is a part number or model # for the relay? Can someone help me out? What should I look for when buying this part?

Is this it? Link to Radio Shack
Descrition says it is 12vDC/30a SPST auto relay. But Aaron Cake said to get a SPDT.
What is the difference?

That looks like the one. SPST = Single Pole, Single Throw. SPDT = Single Pole, Double Throw. The difference is that the single throw is in either one of two positions ("throws,") like a light switch in your house. The double throw can be in one of three positions, like OFF, A, or B. The SPST is all you need to make the antenna work, as the wire from the antenna is either grounded (to make it go up) or not grounded to make it go down.
