Fielder Mountain is an easy 'road' summit in Southern Oregon. With several large RF sites at the top, the road is passable in a passenger car all the way to the summit - however a gate may put you on foot for the last portion. 

Take Exit 48 from I-5 into Rogue River. Head west on Main to Foothill Blvd, and then North on West Evans Creek Road about 2.9 miles. Turn left onto Fielder Creek Road and drive about 4.5 miles to the gate. The road is a bit rougher from here on - easy on foot but it might be too challenging for a passenger car. About 1.5 miles past the gate will bring you to the summit proper - a clearing away from the RF sites is the high point and a good place to operate.
