man that must be a really really long dipole - 10 metres ? the birds are going to enjoy their new hangout spot lol =) the only time i built dipole was at 6GHz, 6cm i think, on a pcb substrate. Why not loop ? you cover a wider range of freq. Or if you must do old school, a yagi uda ? Well, at least you are at low freq, but path breakage and return loss can be a pain in the long run. 30dB signal to noise ratio is very nice too. hope you've got a good filter - harmonics and third order intermodulations can get quite disruptive

It's not that bad. 2x 60 foot lengths + 2x 25ft counterpoise. With a matching transformer.
7E6/(2c)=70ft
Where do yoi get 120ft?
The magic of maching transformers and maching tuners. I use this baby even for 2mhz
true, good grounding and impedance matching makes a lot of diff. but wow, these are like conversations from a diff era lol.
Radio waves have remain constant since the beginning of the universe. It's Era-less :)
Haha, I was having my Maxwell moment last week - his 19th century rf, emf equations are today used from mega power towers, hydro turbine, wind turbines, airplane, MRIs down to a tiny 1mm gyroscope. Just wild.
My antennas are in milimetre range, yours is 36 meters long, the diff is a 50 yrs age gap lol! But very cool, very retro. Have fun!
