Wrong way round  Time owned: 3 to 6 months
Forgot to say in earlier post, my MFJ-907 had been wired in the box the wrong way round, spent quite a while trying to figure out why my 160m whip on an analyser showed base impedance of around 26 ohms, connecting the 907 made it worse, so I reversed it and bingo, perfect matches!

JUST WHAT I NEEDED  Time owned: 0 to 3 months
I COULDNT GET MY WEBSTER BAND SPANNER BELOW 1.5:1 WITHOUT THE 907, I HAD EVEN TRIED TUNING THE COAX BY USING VARIOUS LENGTHS. THE 907 MATCHED THE 30 SOME OHMS OF THE ANTENNA TO THE 50 OHM COAX JUST LIKE IT SHOULD,1:1. THE UNIT HAD TO BE USED AT THE ANTENNA AND DIDNT WORK AT THE RADIO END OF THE COAX AS YOU MIGHT EXPECT. THE HAM I GOT IT FROM SAID HE WAS USING IT AT THE RADIO END, I WONDER IF IT DIDNT WORK FOR HIM AND THATS WHY HE SOLD IT. NOW THAT THE MOBILE SWR ISSUE IS RESOLVED I CAN PURSUE AN ALS-500M. THE 907 WILL HANDLE A KW. 73 KEITH W5YPK

Great results  Time owned: 0 to 3 months
I am using the MFJ-907 with a Hustler RM-20 Standard resonator and DX Engineering Hotrodz capacity hat on 2 of DX's 24" masts for 40 meters. The SWR is 1.5:1 or less from 7200KHz to 7300KHz. Thx MFJ for another great product.

Flat 1:1 on all HF bands  Time owned: 3 to 6 months
When using the MFJ-907 I get a flat 1:1 SWR on all HF bands into my HF mobile antenna. Outstanding item and worth every penny. Visit my web site for full pictures.
