81 degrees and 257 degrees are almost in totally opposite directions. For the UHF stations I would consider an Antennas Direct DB-8e with the reflector removed to get the channels in both directions. For the 2 VHF stations maybe a Antennas Direct Clearstream 5 or (if you can find it) and Antennacraft CS600.
Are there any trees or do you have LOS (Line-of-Sight) in both directions?
Others will post. Wait until they do before ordering anything.
