The 51ft "G5RV" performs well on 40m, 20m and 10m - bands where the SWR(50) at the ladderline/coax junction is moderate. On other bands the SWR(50) is high, and how well it performs will depend on the length and quality of your coax run.

On 40m you will notice little difference compared to a half-wave dipole; on 20m it has a small amount of broadside gain over a half-wave dipole; and on 10m the azimuth pattern has broken into 6 major lobes, with best performance at 45 degrees to the direction of the wire

Using a good CM choke at the coax/ladderline junction is important - it will reduce radiation from the ladderline section and noise pick up on the coax run.

I'm operating from a small lot in Florida winters, I have a 40M dipole up but 
it doesn't quite fit my opening, it is into the branches 5 or 6 feet. I wonder 
what the 51' G5RV would perform like compared to the dipole on 40, and as a 
bonus I might get some other bands...   Any ideas???de Dick  NY1E/4www.ny1e.com
