I would like to get some recomendations as to some good Mag Mounts.  I am looking for a 3 or 4 magnet system.  It must be a quality/well made unit capable of holding a large home made antenna.  It needs to accept a 3/8" x 24 thread.  The mount will be used on different vehicles.  I am current looking at the MFJ-336T Goliath TRI-Mount, because of price mostly.  Anything better out there?  Thanks, Al N7IOH

I don't like magmounts for a variety of reasons. That said, the one sold by Lakeview Company (864-226-6990)is as good as any. it sells for $42.95.

I have the mount Alan is suggesting, it seems to hold steady.  However, I have not had it up for a lengthy trip yet either.  I was told that I don't need to ground an HF antenna mounted with a mag mount, would that be true?  It just doesn't sound quite right to me.

"73's"? What was that supposed to mean?

I've used three and four-magnet mounts for MP-2 and MP-3 antennas. A homebrew mount with five magnets held a full-sized 80 meter Bug Catcher (but the magnets had to be adjusted to the angle of the roof). Another home-made mount with seven magnets (room for eight but I ran out) successfully held up a DK3 screwdriver antenna. Again, the magnets were shimmed to the angle of the roof.

An Iron-Horse three-magnet mount held a Webster Bandspanner (the short one) - but the plastic mount fractured.

Commercial mounts usually don't let the magnets move enough to conform to a curved roof, and are less effective as a result. This shows up in the rear-view mirror.

Your instinct is right. Find a nearby spot, and ground it. It is only above the higher end of the HF spectrum that a ground can be dispensed with when using a mag-mount, and not always then; I've had to increase mount capacitance even at 42 MHz.

KA5S, thank you for the input, I'll give it a ground.  KB9YKY, must have been a slip of the fingers on the keyboard, but don't worry because it doesn't apply to you or others that nitpick on others' postings.

I wasn't "nitpicking". Odd that your fingers would "slip" at those 2 opposite sides of the keyboard at the same time. Seven Threeeeeeeeees. Ha.
