You need an SWR meter and a patch lead. The patch lead should be NO SHORTER than 36 inches, and should be RG-213 or RG-8 coax for best results. you should use the best meter you can afford, or for a single time installation, go to a reputable CB / Two Way radio business. They will charge you for the service, but they will do it properly. The better the SWR on an antenna, the better the RECEIVED signal will be, a high SWR wont affect your Transmittted signal until it's above 6-7 : 1 , and no pre tuned HF antenna will be that bad. The reflected power on a high SWR slows the forward power of transmitted power in a continuous loop effect, effecting the output power up the stick. Put simply, without the 14 lines of mathematical equations, the lower the SWR the better the received signal on both sides...yours is stronger for MORE power going out and not coming back and looping up and down the coax, and the RECEIVED signal is louder due to a better overall matching of antenna to receiver
