<For 2metres

2 metre aerials are required for talkback on the 144.75 Mhz ATV calling channel.
To minimise the number of unweildy yagi aerials in the sky I decided to combine the 23cms slot with the 13cms slot and the 2mtre J aerial. The Bassoon 3 band J-Pole

Note that the two slot aerials are horizontally polarised but the 2 metre aerial is vertically polarised.
