Pretty good little setup and does everything we need and reasonably good value too - good alternative should we be unable to have anything donated. | Pretty good little setup and does everything we need and reasonably good value too - good alternative should we be unable to have anything donated. | ||
We will need a mast to put the dipole up on at a reasonable height, probably guyed. | |||

* Might be able to provide a Klark Teknik Square ONE Dynamics box - 8 channels of switchable gates/compressors, absolutely perfect for quick and simple broadcast mic processing for 4 mics --[[User:JamesHarrison|James Harrison]] 13:48, 4 March 2012 (UTC) | |||
