Linked Dipole
« on: June 20, 2018, 08:29:30 AM »
For quite a time I was interested in building a resonant multiband dipole or linked dipole.
I see a lot of benefits in it, especially no tuner is needed therefore no loss for qrp. Although you have to carry a bit more of equipment, the linked dipole should perform the best regarding noise and stuff - so they say.

Anyway, I got myself the dipole center with a 1:1 balun kit from sota beams.
I found a great tutorial on how to trim the wire :

So in the following days I intend to build the linked dipole and will keep you updated.
I'm quite curious about the performance compared to the random wire end fed antenna. I intend to use this linked dipole with my 6 meter telescope pole.

Sotabeams makes some good stuff. That looks like a nice balun. If you can set up a wispr beacon it might be a good way of doing direct comparisons of the antennas.

I still need a wolphilink for my 817, but yes, thats a good idea for a comparison!
