Including the feed wire into the shack the total length is in the neighborhood of 42 feet.
2 meter gutter counterpoise.
Just wanted let you know that i have using a rain gutter antenna for years with an alligator clip to gutter support a few feet off the ground then 16 gauge wire though window to antenna tuner works very well on 40 meters with my military tcs 12 transmitter and my johnson ranger and my ten triton iv though does not like 20m.
I ran across a video this morning on.
Over a quarter wavelength for 40 meters and almost a half wave for 30 meters.
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 160 meter system might require 16 feet of counterpoise height and that will directly subtract from effective radiator height.
One s unit is.

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.
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.
Please try again later.
Over a quarter wavelength for 40 meters and almost a half wave for 30 meters.
The downspout has a vertical run of approximately 16 feet connecting the horizontal rain gutter which is about 16 feet long across the front of the house.
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.
In terms of effective radiated power erp this means that a 5 watt ht with rubber duck radiates only 1 watt.
