I am not sure if there's an antonym for jam as in "they jammed our radio signals". Is there? I looked up dictionaries and thesauruses and I haven't found a single antonym for the verb jam as in "jamming a radio signal". There are antonym related to different definitions of jam, but not the one I am looking for. What are the words that can qualify as an antonym?

I am thinking there are phrasal verbs or other verbs that are not quite the same as antonyms that could be provided as answers, but I am not sure if these words can technically be used as antonyms.


Intention matters here. Do you want a better signal because the one available is poor? Then amplify or de-noise/denoise work. However, if you want to remedy a jam on the signal, you would unjam it.


I would use "to boost".

According to Merriam-Webster's Dictionary :

 : to raise the voltage of or across (an electric circuit)

Here's an example from Reverso.context.net:

"So you broke into that satellite facility to boost your signal."
