I can't tell the size of the cable since there is nothing near it for scale. I did a search on the E number and found an eBay ad for 75 ohm TV cable. The other numbers on the jacket do not identify the cable type (at least not to me). If you say that the RG59 connector, which is intended for TV cable, is too small - then it could be an RG-8 size cable. But unless you can identify the cable or determine that it is intended for radio use, I wouldn't use it.
