2m/70cm is pretty easy... almost anything that works well on 2m will work fine on 70cm, and a lot of designs are balanced between the two. To get all three though, it gets a bit trickier. Easiest solution is to build/buy a discone. The biggest issue with moving your VHF+ antenna further away is that coax losses are pretty high on UHF.Just got my General license to operate on the entire 10 meter band, so I went for a four band antenna such as this and gave it a shot. it's useable on 70cm except near the end of the band, useable on the entire 2m band, but it's not very efficient, useable towards the CW portion as a terrible 6m antenna, and a very narrow bandwidth on 10m ...A really quick antenna for 2 metres and 70 centimetres, made from just 2 metal coat hangers and a small length of strip connector just add the fun.Next time...I plan on building single antennas on 2m (10 elements +) and 70cm (14 elements +) for SSB and either singles for FM or perhaps co-phased, not sure yet.

Most of the materials can be found at the nearest hardware store or building supply outlet. The antenna is perfect for local traffic and ragchew nets, as well as portable and emergency use.A 2m piece of wire would be a longwire for 2m. 2.5m would make it resonant (instead of anti-resonant, even ¼wl multiple, high-Z) so it wouldn't need a transformer. Then you have to tune it for transmit — tuners are uncommon above HF, so the antenna would have to be trimmed. An SWR meter or antenna analyzer would do it.What you’ll need to make a Slim Jim: Some balanced ladder line feeder – either 300 or 450 ohm will do – If making an antenna for 145MHz, then you’ll need a length of 1.5 metres.
