Was doing some yard work and intended to adjust my 500 feet of wire loop up in the trees...but instead wound up building two J pole roll up antennas from that 300 Ohm FM/TV flat wire or what is sometimes called twin lead.
The first I built as I had always done just a simple 2 meter J pole and it turned out fine.
The Second I built according to some newer plans to be a dual band...2 meter/440 J pole out of the same 300 Ohm twin lead antenna wire.
Both antennas are fed with Super 8 coaxial cable.
Here is the photo of the first 2 meter only J pole when it was completed...
For those readers not familiar with this kind of antenna..the actual antenna is the brown flat line with a brown wire loop to hang it up on the top end.
What you can also see in the rolled up bundle of gray coaxial cable is that the metal connector on the end is made to go on an antenna with a BNC connector. The adapter for the Baofeng type connector is on the table down in the wound up bundle. This adapter adapts from a BNC connector to the Baofeng type antenna connector. With this set up or adapter I can do both types of radios...and also a standard PL 259 type connector too.
And here is a photo of the same type of J pole twin lead antenna inserted into a PVC pipe to protect it when hanging up out in the elements.
These antennas are simple to make and inexpensive too. There are better antennas out there for 2 meters and 70 CM but the costs start going up rapidly for them.
On a budget learning to make your own is a good thing to know.
