 +====== Internal Antenna ======
 +The internal antenna was designed with the small gap above WLAN in the 2.4 GHz ISM band as target.
 +The actual antenna seems to be closer to the lower part of the 2.4 GHz band, though.
 +These are some measurements made with a ZVH8 network analyzer:
 +These show that the antenna of this specific rad1o is most sensitive around 2.36 GHz and is still sensitive up to 2.45 GHz. Above that, the sensitivity starts to drop.
 +This measurement was made with an SMA connector attached to the rad1o and a 0 Ohm resistor bridging the SMA connector to the internal antenna:
 +Please keep in mind that different rad1os might have slightly different characteristics.
