Re: KX3 kit shipping estimate

Kieth,

How about a tape measure beam? I believe 6 meters would be practical.
See http://www.ccars.org/Projects/TapeYagi/index.htm for one example -
increase the size for 6 meters.

Very excited as this will be my biz travel radio. Now need to find a good super ultra penultimatr portable Yagi for 6m that can fit in a standard pelican case. Any ideas?

Re: KX3 kit shipping estimate

I took a minute to look at the links, and I think the 6m yagi would have some problems with droop and the elements folding, BUT Don's idea has a lot of merit.

I think a 6m Halo's (round and square) could be very nicely done with a tape-measure & pvc construction. Also, a Moxon beam might be nicely done with very light weight supports and tape measure / wire / pvc construction…

Re: KX3 kit shipping estimate

I don't get the appeal of tape measure material for antenna elements. Other than its
'self-measurement' property, what's good about it? It is made of steel, which has a
relatively high resistance, and isn't particularly durable.

Re: KX3 kit shipping estimate

Not only that, a five foot long tape measure is gonna buckle when the first wind blows.

Re: tape measure ant / elements

In reply to this post by Vic Rosenthal

flexible but self supporting. as a travel ant, the elements would stow nicely, but when 'rolled out', would remain self supporting

The 1 inch wide tape material is not likely to buckle as long as it is
kept flat and horizontal,
Lowes DIY Kobalt brand comes in 1 inch wide - I have not seen the
refills for that tape, but have not looked either. I can stretch mine
out to almost 10 feet before it drops.

Re: KX3 kit shipping estimate

In reply to this post by Vic Rosenthal

To add to Vic's comment, the connections between the tape and the feeder
would have to be well protected against moisture and rain. Any corrosion of
these connections could result in BCI to nearby FM broadcast receivers - the
rusty bolt effect.

A very neat and sturdy 6m yagi built by a friend many years ago for portable
use, was made of fibreglass tubing. Both the boom and each element support
consisted IIRC of three lengths of tubing, with the outer parts "telescoped"
into the middle part, and locked into place by a bolt, washer and nut.
Each element was made of large guage copper wire, taped to its support
tubing.
