Two Band Fan Dipole

[VK2CSW]

I have started to look at putting a fan dipole together for 12 and 15 metres. My 40m OCF should cover 15 but doesn't and the 20m dipole next to it is now somewhat redundant, so I will replace .it.

I have assembled the balun/choke/centre support.

At first it was RG58 wound onto a FT240-31 core. However it wasn't so effective - around -16dB rejection across the bands in question.

I rewound it with 1.25 mm diameter enamelled wire to get better than -30dB across all of the HF bands.

   

   

This afternoon on my drive home from work I realised I had no anchor points for the second dipole, so rather than anchoring off the same eyebolts I added a second set at the bottom of the case.

I was quite pleased with the end result.
