You need remote tune. With even low power, the voltages on a small loop antenna are very high, in the thousands of volts.
Also, the radiation resistance of the antenna is very low - so, it is essential that the connection to the capacitor be as short and direct as possible.
If it were possible to run some type of cable or ribbon from the antenna to the shack and somehow get the antenna to tune, the loss would be so great that what you would have would be something like a dummy load. And yes, sometime you can make contacts with a dummy load - this fact does not make it a good antenna.
Here are a couple of links on small loop antennashttp://www.standpipe.com/w2bri/http://www.aa5tb.com/loop.html
This second link has many links at the bottom of the page. There is lots of info on the web on small loop antennas. Hope this helps.
