The Dually
This antenna build is two sided, and once complete you will have two full antennas in one. The 49:1 side can be used for end fed resonant antennas, and the 9:1 side can be use for end fed random wire antennas for use over various HF bands with the use of a tuner. I created this antenna with portability and flexibility in mind.
​
I by no means have all the technical knowledge when it comes to antennas, but I understand enough to experiment. I had an Idea that I played around with. This antenna was an experiment that I had great results with, so figured I would offer it up as a new unique offering for hams looking for an antenna with more options in one package.
​
I use this antenna mostly as a sloper with the transformer down low, but there are many different configurations. I don't have all the technical information here. Ultimately it's a 49:1 and a 9:1 unun. You can find tons of info online on these antennas for what wire lengths to use and configuration possibilities.
​
But if you want to keep it simple for now. you can use it as a sloper with these approximate lengths of antenna wire with a 50ft length of coax with a choke close to the radio.
49:1 side approximate antenna lengths - 33ft, or 65ft
9:1 side approximate antenna lengths - 29ft, or 41ft

Power - I know the antenna will take 100 watts SSB. I do not know for sure how much it can handle CW and digital
