Hi Ralph,
This is totally unsubstantiated with any personal "...blood, sweat, & tears"
on my part, but I recall reading somewhere years & years ago (the "NCJ",
maybe...?) that in order to experience any detectable/noticeable benefit in
making your tower taller, you have to at least double the existing height...
Increments of one, or two, sections just doesn't cut it, apparently...
...But I defer to the real-world experts reading this who have first-hand
practical knowledge & experience in all this...!

on a Budget" column. The topic will be to look at the benefits, costs, and
considerations associated with raising a tower from 50 feet to 70 feet.
Here are some of the thoughts I have:

> Benefits:
>
> You will hear and work dx which was previously unavailable. My estimate
is that you will add an S unit.
>
> Occasionally get to run dx, especially during non-contest times.
>
> Be able to raise your lowband antennas.
>
> Add the possibility of mounting a tribander in a fixed direction to add
contest flexibility.
>
> Possibly decrease RF in your shack and get rid of unresolved problems.

> Considerations:
>
> If you live in a hill, or have a good view, perhaps there will not be as
great a benefit.
>
> Now you always must use proper safety equipment when climbing.
>
> Perhaps this is the time to replace coax, or go to a bigger antenna.
>
> It becomes more noticable
>
> Is a permit required?
>
> You will need to locate a gin pole for the last few sections.

> Could your signal be worse to certain areas?

> Costs:
>
> Probably you will be moving away from the simple house bracketed tower and
will have to add real anchors and guy wires.
> You might have to relocate the tower and use two sets of guy wires.
>
> Two sections of tower, turnbuckles, clamps, rotor cable, coax, tape

love to hear from you and learn what you came across. Thanks.
