About this video
Today we will be talking about the BD7IBI Telescoping Ham Radio and Shortwave Listening (SWL) Antenna. This is a Antenna capable of 20m-6M. Although this one is $21.00 USD, it does not come with the M10 too 3/8 24 thread adapter (which should be easy to find). Additionally, there are a lot of different variations of this on Aliexpress, some which come with the adapter for a buck or two more, some that are only 16$ USD.
please note: I forgot to mention you can use it with Coil for more bands, but as it sits, it could be used for a 20m 1/4 vertical (with radials)
If you want to get to the point, you can skip ahead to the end.
