I am using a whip antenna mounted on a metal patio cover. Results are

longer whip is under consideration). It is fed through an antenna tuner

Something for consideration for lengthing the whip: Buy a 3 or 4 ft 3/8 inch
aluminum rod from local hardware store and thread it on both ends with
3/8x24. Use a coupler nut to fit it to the bottom of the whip. I've used
this technique with mobile antennas and seems to work fine.

Also, you mentioned the ability to use open wire/ladder line. Wonder if you
considered ladder line to a 4:1 balun and then short coax to tuner? I'm not
sure that presently with such a short run of coax to the patio you would
gain much, but for longer runs, it would definitely be a consideration.
