[TowerTalk] End Fed Half Wave Noise Remedy

[Tony]

All:

I use an end-fed half wave for portable work and was wondering what the 
most effective way would be to reduce the ingress of feed-line noise? 
I've compared it to a resonant center fed dipole in the field and found 
the receiver noise to be higher on the end-fed: same location with the 
same feed line.

I've tried a single choke at different lengths along the feed line which 
does seem to reduce the noise to some extent, but I'm wondering if 
adding several chokes at some specific interval would be more effective.

The antenna is usually deployed with one end in a tree with the 
feed-point a few feet off the ground. I suspect that grounding the feed 
line at the feed point would help, but a ground rod is not particle in 
the field.

Thanks,

Tony
