If my experience is any indication, you may have have RF feedback issues (if you transmit).
If you use an external tuner that probably means that you will have some length of feedline between the rig and the tuner and antenna.
In that configuration, I need to be about 12 feet away from the antenna and have an RF choke inline at the antenna with the counterpoise running in the opposite direction for success.
For me, it rules out having the antenna inside the tent.
