I think my situation is very similar to yours. My antenna (a "130 foot doublet
up 80 feet" when fed on 80 and up, but when I tie the feedline together at the
base it becomes a "Marconi T for 160M transmit") comes down at a corner of the
house. That corner of the house is surrounded on:
90 degrees by backyard
90 degrees by driveway
90 degrees by garage
90 degrees by house
What I do is run radials off in all directions.
In the 90 degree sector taken up by the garage the radials are laid across the
garage floor, go out the garage windows, then across the driveway and yard.
In the 90 degree sector taken up by the driveway, the radials run across the
top of the blacktop driveway.
In the 90 degree sector taken up by the house, the radials run across the
basement ceiling, through the crawlspace ceiling, and then out the other side
of the house to emerge and be buried through the rest of the yard
In the 90 degree sector taken up by the yard there are buried radials.
The garage and driveway radials are rolled up in summertime (although
redeployed for summer stew).
In no direction do I have a quarter wavelength. The shortest radials to the
edge of the property line are 30 feet, and the longest ones are about 80 feet.
There are about 40 radials in all, a mix of copper and aluminum electric fence
wire.
As to performance... I have compared my signal strengths with other east coast
contest stations into EU and western US. So have the contest stations. I feel I
am an "alligator" with regards to 160M performance right now, I have a great
transmit signal, but need to work on my receive system. Right now I have a K9AY
loop and a west facing pennant and feel I still have a long way to go, to get
to some phased loops for certain important directions.

Thanks Eddy,
Rudy's work is excellent and I've studied much of it in detail!
My question, in-artfully posed, related to the impact of the house on a ground
radial system, not elevated vs . Ground radials.
All the best!
