so ive been going back and forth on this for like three weeks now and i just need someone to tell me im overthinking it. i have a decent sized backyard, probably 80 feet usable in one direction, and im trying to decide between putting up a simple 40m dipole fed with ladder line or just doing a vertical with radials. my main interest is working dx and some casual ragchewing, not contesting or anything serious.

the thing that keeps tripping me up is the takeoff angle stuff. i know verticals are supposed to be better for dx because of the lower angle radiation but ive also read a lot of posts where guys say a dipole at decent height works just as well or better. my supports are a 35 foot tree on one end and i could probably get a mast up to maybe 30 feet on the other end. so the dipole would be kind of a low inverted V situation which i know changes things.

the vertical option would be a cheap GAP or maybe just build a quarter wave with a bunch of radials. i have plenty of wire laying around. does the radial situation really matter that much if im just doing this in a backyard? ive seen people say 16 radials is the magic number and others say go to 32 or more and i dont even know if i have room for that many without them being too short.

anyway any thoughts appreciated, i feel like ive read so much contradicting info that im just going in circles at this point

honestly you probably are overthinking it a little but thats fine, we all do it. here's my take after running both setups over the years — at 35 feet an inverted V on 40m is not a bad antenna at all. yeah the takeoff angle is higher than a vertical but for 40m that actually works pretty well for regional contacts and even decent dx once the band opens up. the practical difference between a low vertical and a low inverted V is often smaller than the theory makes it sound, especially if your radial system isnt great.

and thats the thing about the vertical — the radials really do matter a lot. a quarter wave vertical with only 8 or 10 short radials can actually perform worse than your inverted V depending on soil conditions. 16 is a reasonable starting point but theyre most effective if theyre close to a quarter wave long themselves. if you dont have room for decent radials the dipole is probably the safer bet to just get on the air and start making contacts.

if i were in your situation id just throw up the inverted V first, its cheap and fast, and see how it plays. you can always add a vertical later and do a real world comparison. all the modeling in the world doesnt beat actually listening to the difference from your own location.

had almost the exact same debate last year. went with the inverted V and tbh its been fine. worked a bunch of eu and some jA on it during good openings, nothing crazy but enough to keep me happy. i think people overstate how bad a lower dipole is for dx. the vertical might squeeze out a few more dx qsos but if your radial situation is mediocre you're just trading one compromise for another.

one thing i will say is the ladder line fed version gives you a lot more flexibility if you ever want to try other bands without retuning everything, so thats worth factoring in. my tuner handles it pretty well from 40 up to 10.
