I need some help. I am moving to an apartment with a patio. I have a dualband Kenwood TMV71 and would like to match an antenna for the patio. It will have a 25' feed line. The building has restrictions, so it has to be discreet. I was thinking of either doing a Diamond mobile antenna with a mag mount on some type of metal table. Or, a diamond X50 or X30 base antenna mounted to a mast hidden in a flower pot. One of the concerns is the height. In my best guess, there is about 8 to 9 feet between my patio to the one above me. With a typical patio railing of about 4.5 feet in height. So an antenna like the X50 at best would be about 4' above the (metal) railing, and the rest would be below the railing terminating at the flower pot. The patios in NYC are not huge. Im worried the metal railing would detune the antenna as almost half would be below the rail. And sitting in a flower pot most likely it would be no more then 2' from the railing. I could go with the X30 which is only about 4' tall.I would lose some gain. Or just put a 1/4 wave on a mag mount and call it a day. Any pinions?
