Hi Everyone,

I built VHF/UHF Dual band TurnStile antenna based on explanations on :

https://www.vk4adc.com/web/vhfuhf-projects/26-multiband-ants/156-turnstile-vhf-uhf-fds

Unfortunately I cannot be able to get any signal on UHF side.
On VHF side, I can able to get some signals but very weak…

Any recommendations?

Thank you!..

You will probably want a low noise amplifier (LNA) as near to the antenna as you can mount one. This is what I use for my station (and the same seller offers a bias-t if you want to power it through the coax):

Do you happen to have a link to the seller? The product page is missing now, I get an error page instead.

Hi,
Take care of the connection of stubs to the dipoles, which determines the polarization (rhcp/lhcp).
With wrong polarization, you won’t be able to receive nothing
