At 5MHz you have a wavelength of approximately 60m. So for a dipole antenna (the most basic) you'd need approximately 30m of wire.
You'd have a length of coax cable going to the centre point of the antenna, so pair of 15m wires extending from each side.
Getting your amateur radio license covers this in more detail.

- cschneid 2y agoA dipole is a very simple antenna, and pretty efficient. There are other shorter options that have worse performance too, but perhaps more suitable for an adhoc tree deployment. (random wire, EFHW) (I know you know this, but just adding in. Ham is fun! I like doing park & camping deployments)
