so ive had a gap titan vertical in the backyard for about two years now and honestly im starting to wonder if i made a mistake with it. it works, dont get me wrong, but i keep reading about guys running simple wire dipoles and working dx that i just cant seem to crack with the vertical. my noise floor on 40m is like S5-S6 most evenings which im pretty sure is the vertical picking up all the local garbage since its basically a noise collection device pointed straight up at the neighborhood.

anyway ive got a decent sized backyard and a couple trees i could use, probably get a center at maybe 30-35 feet which isnt great but its what i have. wondering if anyone has done a direct comparison between a trap vertical and a simple resonant dipole at low heights, like whether the lower takeoff angle from the vertical actually matters at that kind of tree height. i know 35 feet on 40m is pretty low electrically speaking but the noise reduction alone might be worth it. or should i be looking at something else entirely

the noise thing is real, verticals pick up everything especially if your ground system isnt exceptional. i had a similar situation with an R7 years ago. switched to an inverted V and yeah the DX performance dropped a bit on the low angles but i could actually hear the stations i was trying to work which kind of matters. 35 feet for an inverted V on 40m isnt ideal but its workable, just make sure your feedpoint is actually at the peak and not drooping too much or your angle gets even worse. also check your coax shield for common mode current, that was killing me for a while and i thought it was the antenna when it was really just RF coming back down the feedline into the shack.

honestly i went through the exact same thing last year. gap titan to a fan dipole. the rx difference on 40 was immediately noticeable, like night and day quieter. i didnt do any super scientific comparison but i felt like i was working about the same amount of dx, maybe slightly less on the really long haul stuff to JA and that region but more than made up for it by actually being able to pull signals out of the noise. one thing though, the fan dipole took me a couple weekends to get tuned right because the elements interact more than i expected. if you go the simple single-band dipole route its a lot more forgiving to build and adjust
