Hello SOARA Elmers,

 

I am trying to get on 40,20 & 10 meters using my new FT-891 and it's
matching FC-50 auto tuner.

 

Here is path I have taken so far and the constraints of my situation:

 

*	The antenna I hope to use is the End Fed Half Wave Antenna

*	The Facebook Group "End Fed Half Wave Antennas
<https://www.facebook.com/groups/1850555008534519> " provides instructions
for construction
*	This rather lengthy video

ygoXC8dwh38X-nz-KAoWnyiaX4HJW4H55r3ts>  created by Steve Ellington details
how this works and the benefits thereof
*	Uses self-built 49:1 Auto Transformer which I have already built
(see attached)
*	67' wire should work for 40-10 m
*	137' wire should work for 80-10 m

*	I want to use this type because:

*	I live in HOA neighborhood   
*	Lots of trees as I live in the forest
*	I hope to string up wires into trees for stealth
*	End fed allows for easier hiding
*	This map
<https://www.google.com/maps/place/22061+Trailway+Ln,+Lake+Forest,+CA+92630/

27aeec19d72b1!8m2!3d33.6419714!4d-117.694289>  gives you an idea of Location
and tree situation

*	I need to borrow and antenna analyzer 
*	I need advice on how to best configure the wire 
*	I need confirmation on transmission line strategy
*	I need confirmation on grounding strategy
*	I need advice and confirmation on general shack setup
*	I want this system to be repeatable and reliable 

 

I really appreciate any and all help with this project.

Thanks
