You may have not been following all the mish mage of posting about this tree 
antenna, so I'll recap: This all got started when I found that my std active 
antenna design was overloaded to the Nth degree when I mounted it in a tree 
back in the woods because the signal levels were so strong. (The tree acts 
as a very large conducting body with ~2kohms to gnd). Then I removed the FET 
amp in the probe and installed a 10 to 1 transformer and found there was 
plenty of signal to meet the MDS level of the R-75 (so no amount of 
amplification would help in receiving weak signals). Now there's no IM of 
the strong stations against the week ones, typical of a broadband active 
e-probe (particularly from the strong AM stations in this area), AND I have 
never seen such a low neighborhood 'trash noise' factor, which has always 
been a problem here. Right now I'm doing an A/B test against my amplified 
woods loop antenna and I'm suspecting the tree probe will do a better job. 
Will let you know.

Bill
