Wouldn't the pitting give the antenna more surface area, broader bandwidth,

What is a good cleaning
Auto part stores carry Aluminum wheel cleaner, it is a strong chemical that
strips off oxidation and leaves a clean , raw, surface. The only problem is
that raw aluminum starts to oxidize immediately. You will need to covert the
antenna with a coating of clear urethane to stop this from

I haven't seen it mentioned yet, but yes, this sounds like a classic

I don't think it is classic intermod. Think about it. The deviation

Usually putting the TX up high is backwards?
Depends on which made for hams stuff you're talking about. Would you
consider a comercial low band radio that normally includes the 6 meter
band as being made for ham? Aside from the above it's pretty easy
to move a lot of commercial radios up to the six meter band.
Actually... as hard as a

I'd rather not use a ham antenna in the commercial bands.
Are there some that'll do the 136 to 174 split, and some UHF that'll do

If you find one, it would have to be pretty low gain (like Unity).

Not really... but as the nature of the bandwidth beast is dealt
with... the 4 dipole antenna gain is not super high (about ~3db).

There are a number of old post on this subject. Take a look at the 4 bay

whether or not they are expensive is a matter of personal opinion.

I have always steered away from Xantrex controllers, primarily because of the
pathetic temperature specification: 32F to 104F. I have a remote cabin in
Ontario, Canada that has to survive on its own during the winter with
temperatures well outside that range. I suspect many remote
Hi John,
You might check on the newer generation of C series charge
controllers. The spec on the new C60 is pretty good and I'll have
a new C40 next week to beat up on.
Construction is pretty good for what it is. I can't see any reason
why it won't perform well past the mfgrs rated spec.
Anyone have one they are willing to part with?
Thanks,

You might try ZoopSeal. this product is used on aluminum wheels, valve
