Poorly designed  Time owned: 0 to 3 months
I just acquired this switch for an estate and, while I like the layout with all lines coming in/out in the same direction, I find that all the SO-239 connectors are mounted with pop rivits. These are poorly installed resulting in most connectors being loose to the touch. Sorry MFJ, the smae current must flow through the ground side. To use this switch, I would first solder a copper line to the ground side of each connector. Buy something else.

No problems  Time owned: more than 12 months

good construction BUT  Time owned: 0 to 3 months
purchased this switch to replace a 20 year old B&W model 593 3 position switch i rescued from my junk box. Upon installing the MFJ i saw my VSWR reading jump way up from the B&W. I took the case apart and found a capacitor across the input SO-239 which must have added capacitive reactance to my feedline. I removed the offending component from the circuit and the SWr readings returned to acceptable.. I bypassed all switches and obtained the same vswr so the cap was the problem, otherwise nice construction for $45...

not a good choice  Time owned: 3 to 6 months
- did an A/B/C comparison of this MFJ product (which has six positions); the Alpha Delta Delta-4 (with four positions), and the Diamond CX-310 (with three positions)...

- the Delta-4 and CX-310 effectively isolated incoming signals...

- NOT SO with the MJF 1701!

- so be warned: although the MFJ 1701 may work fine for your application, I believe most hams would hear the difference and would want the more effective switches by spending the extra $20...

- btw, the Diamond is extremely well-made... cast, formed, painted, w/quality components - up to commercial quality, not the sheet metal-stamped travesty of the 1701... (if incoming signals aren't isloated, what do you think will happen if you transmit at higher than QRP levels through the switch?)

- YMMV, of course...

Looks good, works well, decently made  Time owned: 3 to 6 months
I pretty much have to agree with everything the previous reviewer wrote. I bought mine at a hamfest because it was reasonable and have used it to switch between different HF rigs. It looks good, appears to be quite well made, and it has been problem free. It is a bit lightweight in feel. Still, with six positions you don't have a lot of choices at a decent price. Dollar for dollar you can't beat an MFJ-1701.
