WA5VJB makes a PCB material log periodic that works well on 440 Mhz and is quite compact. I have one here and use it to listen to repeaters in this area. its quite directional. I taped mine to a piece of posterboard to protect it and make it easier to handle. I would guess it has around 9DB gain and the 70 cm band. It also works on higher bands. It was a good value at around $15. It covers 400-1000 MHz.
It would likely vastly extend the range of a HT like the Baofengs. It would seem to me to be almost a sure bet it would be useful to you your new hobby. If you use 440 .
