Don't be too much worried with the TX antenna. Under normal circumstances 20 meters its a piece of cake for the transmitter used on our TX units.
Follow hornychz advice and start by trying one of those small 433Mhz antennas attached directly on the SMA connector of the TX board. Carefully plan the box to install the TX board inside, a big waterproof plastic box will give you more options.
More important may the the receiver placement.
