Thats a 3 gang device, you can combine them or use them independently to get the value range you require.
Cant help without knowing the size of your loop, the bands you require and the values of gangs.
I assume its a RX only loop? It will be no good TX unless QRP

If you just want to experiment, just use one of the gangs and see what happens, then a different one, then parallel a couple of them up etc

can you tell me the mesurments the loop should be for80 40 and 20 metre bands please. thanks for replying.... the loop is for rx only...this is another one that I have

Loop size isnt too important for RX, google RX loops there are plenty of examples,
http://ac0c.com/main/page_prior_antenna ... _loop.html shows one of many examples that have been knocked up.
