I purchased a 4' Francis pre-tuned cb24 hotrod antenna recently. First antenna for my first cb radio a president McKinley. On the specs for this antenna it calls for 18' of RG58 cable. I have a place in town that sells all sorts of cable, so I order 20 foot of Belden 50 Ohm RG-58 #8240. I also bought some pl259 connectors. I paid for it all at the counter and the warehouse guy brought the cable to me in a bag I take off, get home, look in the bag and this stuff is SUPER thin. WAY thinner than cb antenna wire I have seen in the past. In fact it's so thin that I don't think it will work with the pl259 connectors I bought. I could probably fit 3 ends of this cable into the pl259 connector sleeve. What did I do wrong? Go easy on me, I'm new to all this.
