2 meter gutter counterpoise.
Although the drake r8 s signal strength meter is marked with silly s units the alignment procedure in the service manual actually sets up the meter to an absolute standard at least sort of.
Over a quarter wavelength for 40 meters and almost a half wave for 30 meters.
The downspout has a vertical run of about 16 feet connecting the horizontal rain gutter which is about 16 feet long across the front of the house.
A 160 meter system might require 16 feet of counterpoise height and that will directly subtract from effective radiator height.
Projections indicate this system should be within 1 2 db of sixty radials 100ft long although optimum performance might require counterpoise heights as much as 0 1 foot above earth per meter wavelength.
One s unit is.

Including the feed wire into the shack the total length is in the neighborhood of 42 feet.

The national bureau of standards tests of public safety high band and amateur 2 meter antennas indicate that a rubber duck has 5db negative gain compared to a quarter wave held at face level.
A 60 modulated signal with a carrier level of 73 dbm which is really closer to 72 dbm in total power including sidebands is s9.
In terms of effective radiated power erp this means that a 5 watt ht with rubber duck radiates only 1 watt.
