SD receiver with HD antenna
We keep our boat under cover where the KVH antenna does not work until we get out of the shed and underway. The marina has now installed a directv for all of the boats under cover. The recondition is now telling that because it is HD it will not work with my SD receivers. He wants me to get a new Directv account with new receivers that will not work with my antenna when I am away from the dock.
The question is can you use SD receivers with an HD antenna and if so, why can’t I use an A-B switch to choose the antenna to feed them.
