Ignore the Youtube UHF antennas, your requirements are completely different since you're looking for VHF, not UHF. You'd have to rescale the coat hanger antennas by a factor of 2.5 to 4X for VHF.
Our simple VHF Retro Fit Kit may well do the job. It's a dipole that's tuned to 195 MHz (ch 10) and there's very, very little drop off in performance on channel 8. If not, you will need to step up to a more directional array of elements to get better reception of a single VHF channel. An additional resource for designing your own is at
