What band(s) are you trying to work? That length kind of close to a quarterwave for 40 meters. If you're trying to make it multi-band then 36 feet would be a better then with a 9:1 Unun. Let us know what you're trying to accomplish and we can give you a better idea.
I would recommend a 9:1 transformer and use a 1:1 choke b4 it enters your shack. The choke will help with noise that wire antennas are known for and they help choke off any RF running down the outside of the coax back to your station to help prevent those nasty RF burns. Ouch. With this long-wire it makes ã excellent HF receiving antenna. When used for transmitting you DO need ã antenna matcher or impedance matching device. The antenna tuner that is installed in most transceivers should work fine. Even the fussy ones.
Below are some wire lengths you can experiment with. 53’ seems very common and if you have the realestate 124.5’ maybe better.
