[TowerTalk] RX 4square active element

[fabio.grisafi at libero.it]

Hello Guys!

I wish to build an RX four square for 160-80 mts.

The design I want to duplicate is the DXEngineering system.

I have enough experience to do it but I wish to know what kind of active element we should use and how to connect the verical element to a preamplifier and what kind of preamplifier to use.

Thank you,

Fabio, IT9GSF.
