content: I think he's after the ferrule. Just add fibreglass rod, wire and heatshrink to make his own whips.... to be fittedtoa base.

content: I've had a bit of a look around and there are a few things you could look at, but nothing stands out. Many with male thread mounting and most seem to be for solid rod radiating elements of 0.1", 0.125" or 0.2" dia.Unless someone here who has their finger on this pulse responds, you might have to do some Googling yourself to see if something jumps out at you. The key word is "ferrule" (are there other words used?). Just try combinations with "whip", "antenna", etc. and see how you go..... (that's all I've been doing).

content: I forget where we used to get these ferrules and did search around without any luck retail wise as a separate item although you can buy a small whip for around $15 with the incorporated ferrule, I haven’t used these for years and thought I still had a few out in the workshop but after a quick look I couldn’t find them, we once used these for stainless two meter whips and some were never used, I'm pretty sure they are all 5/16-26 TPI thread but you can also get larger ones which will have a 3/8-24 TPI thread.If you have no success in finding them or the price is completely out of order then I could probably knock a few out on the lathe but would need to know the required diameter and depth of the centre hole in addition to the number of grub screws you prefer if any as fibreglass whips will be glued using epoxy and stainless rod will be secured with the grub screws. The options would be brass, steel or stainless, the steel will rust and the stainless might be a pain for me to tap in a blind hole, the brass would be best and the male bases all have a brass thread anyway.

content: Oh sure! Just "knock out some on my lathe".In my hacker space, been trying to remember how not to hurt our donated lathe.Though I took high school metalworking lathe courses, and adult ed after school, still put it behind my welding skills needed.Yes, I watch the steam train lathe guy like my wife watching cooking shows, we can all aspire.

content: Quote from: Shock on July 12, 2016, 04:47:56 amI thought circling a picture would be like a "this thing right here! not the thing above or below but this!!!"had no idea what it was called and googling any possible thing "antenna nut" "antenna base nut" "why you no give me what I want" didn't return what i wantedThey seem to be a bit difficult to obtain... Maybe getting a cheap antenna and pulling it apart may be the solutionor manufacturing some on a lathe... I do have some brass rods here which could do the job.. Now to get a latheWell I mustn't give up!

content: That one has the male thread for the mounting. Lots of those around. The OP is after ones with the female mounting thread.

content: That thought crossed my mind as well - perhaps something shorter than that 4.5" one - but I presume the OP might have their reasons. Besides, more joins = more points of failure.
