I put up my Comet CX-333 Triband Antenna (2m, 1.25m,70cm) about 2 weeks ago. Its base is about 17' above the ground (tip at around 27'). I ran about 28' of LMR-400 Ultraflex from the radio to the surge protector just outside the house and then another 37' of regular stiff LMR-400 to the antenna (total of 65ft of LMR-400). The antenna seems to work quite nicely on all three bands. I checked the SWR in the middle of each band and I got: 2m = 1.6, 1.25m = 1.4, 70cm = 2.0 As a new ham, I was interested in understanding this more, and so a friend came over with their RigExpert antenna analyzer. The reality is the the SWR curve is significant over the entire bands: For 2m, the curve ranges from roughly 2.0 to 1.1 with the low around 147Mhz For 1.25m, the curve ranges from about roughly 1.7 to 1.2 with the low at about 224.5Mhz For 70cm, the curve has a series of 5 or more peaks and valleys (it is a relatively wide band), ranging from roughly 2.5 to 1.1, with the low at about 433MHz. Obviously, the cable run, surge protector, quality of the connectors and other factors make a difference. But for me, a new ham, understanding how the SWR actually varies significantly across the band was interesting. We also ran a TDR test, and that is also interesting as you can see a tiny bump where the surge protector is in the middle of the line. As it is, I like the antenna!
