Gen2 of the NY4G End Fed Half Wave

 

Generation 2 with the following improvements:

Winder is separable from the transformer so it can be replaced if damaged or if one that is impervious to weather is desired, a plastic one may be substituted

The end caps are now made of aluminum instead if walnut.   This gives more ruggedness to these parts.




Picture shown below is during testing and pruning for best balance across the bands.


Walnut winder and transformer box


88 feet of wire in the air for 60m operation.  The 60m extension is separable so that the 40-20-15-10-6 can also be deployed - resonant on these five bands


Walnut transformer box and white UHMW winder


Pruning and VSWR scans - the following are typical from the bottom end of each band

to the top portion of the band
