That is a great idea.
I might be able to something along those same lines with my ALA1530S+ and the ALA100LN. But since the 43' wire on the ALA100LN is stapled to the house, the ALA1530S+ will have to be rotated to N-S and that' the only position that the ALA100LN can go, unless I restaple it to the E-W part of the house, but then closer to the underground power & mostly pointing right at it. Or... move the thing on the other side of the house and staple it to the garage, then the underground power won't be an issue (in theory). And there is already an old coax running out there (just need to find where the inside end goes).
