@larry, the antenna soldered right on he board was for initial test only... on the other hand, my antenna guru told me that the connection from the board to the antenna should anyway be as short as possible... so I'm thinking to put all - including an Espruino, power pack and other electronics in a little box with solar cell attached and all mounted just below the antenna radials - up on a pole 10..12f / 3..3.6m above ground. For the (ground) sensors, this 10..12f / 3..3.6m wiring should not be an issue for the protocol (i2c).
