cheap solution  Time owned: 0 to 3 months
I had RFI problems with my indoor setup at the city condo. to work 40 meters was impossible without reducing the power to qrp-level. after installing the MFJ-915 the problems are gone and I can work "QRO" without getting burned.

Helps really!  Time owned: 0 to 3 months
At time I can only use a wire with 40 feet and 2 Radials with abt. 12 feet in the attic. To get better impedance I use a Unun 1:9. The tuner is a MFJ-945e.

This "antenna" works not so bad as I suspected, but I had a lot of RF in the shack, e.g. on the case and microphone of the rig. Especially on 40 and 80 Meter the RF sometimes hurts on the lips, hi.

So I tried this MFJ-919 RF Isolator and I was really impressed! No RF in the shack and the efficiency of this antenna gets noticeable better.

So I recommend this unit.
