so i finally bit the bullet and built my first dipole from scratch this weekend. been putting it off forever because i kept thinking it would be more complicated than it is, but honestly once i just sat down and did it the whole thing took maybe two hours including running the feedline.

i used some 14 gauge stranded wire i had leftover from an old project, cut each leg to about 16.5 feet for 40m, and used a choc block connector in the middle as a temporary center insulator which i know isnt ideal but it was what i had lying around. fed it with about 30 feet of RG-8X into my tuner. threw it up as an inverted-V with the apex at about 25 feet off a pushup mast.

swr on resonance came out around 1.4:1 which i was pretty happy with for a first go. trimmed about 4 inches off each leg to get it there. resonant at 7.15 which is right in the middle of where i operate most anyway. made a contact into ohio from upstate new york first time i keyed up so i figured that was a good sign.

wondering if anyone has thoughts on what to do for a proper center insulator — i see people use SO-239 connectors with a piece of pvc or a section of cutting board. is there a preferred way to do this or does it really matter as long as its weatherproof?

the cutting board method works really well, ive been using a piece of white hdpe from the kitchen section at walmart for years on my portable dipoles. drill two holes for the wire legs, one in the middle for the feedline, put a drip loop on the coax and some self amalgamating tape over the connector and you're sorted. the SO-239 approach is cleaner but honestly either works fine if you keep water out of the connector.

one thing i'd suggest — if you're leaving it up permanently, swap that choc block out sooner rather than later. water gets in those things and you'll have intermittent issues that drive you crazy trying to diagnose. had that happen on a 20m dipole i built years ago and spent a whole afternoon thinking my radio was acting up before i figured out it was a corroded connector at the center.

1.4:1 on a first build without a lot of fussing is actually pretty decent. some guys obsess over getting it to 1:1 but at 1.4 your radio is perfectly happy and you're not losing anything meaningful. nice work getting it in the air and actually making a contact — that's the whole point right there.
