Is budget an issue? How much? If you're going vertical, go with the open land.
RECEIVING: I would recommend Beverages to start for receive, and if you can afford it...a HiZ receiving array spaced for the low bands (since prop is favoring those in the coming years). For separate receiving antenna in this scenario, recommend a DX Engineering RTR-1A. Also, you may want to have an SDR for receive like an SDRPlay unit for under $200. Then you can monitor it using a simple Linux machine nearby with WebSDR software...and broadcast the packets that will allow you to receive them and control the SDR receiver using a simple web browser!
TRANSMITTING: That leaves the transmit piece; most modern rigs (since 2000) already have remote capability over the internet. Since you're only transmitting with this rig and not receiving, you just need a way to get audio or digital or CW TO the rig. RCFOrb has freeware that can do this already. hen you just need a separate transmit antenna. An inverted L with remote tuner at base, away from the HiZ receiving array, would do it. No radials needed for the receiving array, and it's simpler than a transmit/receive four square. And the inverted L (with radials, of course) can be used on all bands, That's what I have at my QTH.
