front side back side. Sold as a kit for $25 USD, this is easy to assemble and has an SWR indicator built into the tuner. The hole in the top allows tying this off away from the operating position. Add wire, tune for best noise - switch to TUNE and rotate the knob until the SWR LED goes out. Easy-peasy to use. Built-in 5W dummy load for tuning. Nice touch. On the front of the unit is a small chart showing wire length for antenna and counterpoise. So simple, it's hard to add much more than this - I built one, I use one - it works. Assembly manual - requires some soldering and winding a simple toroidal coil. Vendor site
