onelinkmore BNC Female to Dual Banana Female Socket Binding Post RF Coax Splitter Adapter Connector for HF Radio Antennas Pack of 2

Like everyone else, I used this to make a 20 meter QRP dipole antenna for my portable operations. I used a 3/16 drill bit and drilled a hole between the terminals then attached a carabiner clip to it so there would be no strain on the wire. I used about 17' of 20 gauge wire for each side and deployed for fine tuning. I was able to trim the ends to get the phone portion of the band to 1.0 SWR and the digital portion of the band to 1.2 As you can tell, it has a low Q (wide bandwidth) to cover the entire band without an antenna tuner. It would not be resonant on any other band without one. Since you get 5 to a pack, make 5 bands. Also in the picture I have a female BNC to SO239 adapter because all of my cables are RG-8X with PL-259 ends. These things are great for dipoles. Between wire, carabiner and adapter I have less than $10 in it and it works amazing and is super light weight.

Good quality at a great price. Now I can make a couple of inexpensive yet great performing dipole antennas !

Keep these around for making dipole antennas. Solid kit.

Good quality and work well. Used them to adapt coax to the antenna terminals of a vintage shortwave receiver.

I used one of these binding posts to make a super simple speaker wire dipole and talked to people across the country (and in another country). It worked great for my purposes and didn’t break the bank.

Seem okay for chinesium

They allowed me to make portable antennas for HF work while on vacation. Made contacts with Belize, Costa Rica, Trinidad & Tobago, and Florida from the Georgia/Tennessee border using these, some wire scavenged from Ethernet cables, a 21-foot Tenkara collapsible fly-fishing rod, and some coax.

This works great for a quick up antenna for POTA or temporary emergency communications. I don't think I would leave it up permanently. It is good for what it is, temporary antennas.
