[SMCARA] What to expect from a G5RV....

[Richard (KG3BOZ)]

Thanks.  

I did read about this 'optimized' G5RV.  I'd be interested to see some actual antenna measurements (with calibrated test equipment).  I'm not sure I am ready to believe all of the claims on the website. 

Having said that, what really counts is whether the user enjoys the antenna performance. Everything else is academic.

Just so everyone knows, Dave is not working with a regular G5RV.  He
is using what is called a ZS6BKW G5RV, or an Optimized G5RV.  Slightly
different antenna, that was optimized by computer modeling off the
original G5RV.   

You can see what it looks like at the bottom of this page, and under
the regular G5RV.  http://www.w8amz.com/W8AMZ_G5RV_Page.html [1] 

The ZS6BKW as I was optimized to be better than the original G5RV
antenna, and is capable of operating on 10, 12, 17, 20 & 40m bands
generally without a tuner, with SWR readings usually 1.5:1 or less. 
Using a tuner 6, 15, 30 & 80m bands with much higher efficiency then
the original G5RV.   

I researched this antenna a good amount before I purchased it, and
this is a .pdf that details a comparison between the G5RV and the
ZS6BKW.

Just wanted to through this out here so everyone was on the same
page antenna wise.

  Tom Rausch, W8JI, a noted engineer and designer of ham products 
discusses the G5RV...
http://www.w8ji.com/g5rv_facts.htm [3]
In particular he comments:
"...The G5RV has a _reasonable SWR_ on 80, 40, 20, 15, and 12
meters./It 
is not an acceptable performer on 30, 17, or 10 meters/.'
and:
"While the G5RV requires an antenna tuner, it is very efficient on
at 
least 5 bands."
