Need design info on coax traps for dipoles
Good afternoon... Anybody know where I can find some formulas or design information for designing coax traps for a dipole? I've seen some articles on coax-trap antennas but the traps they use are too big. I need to make some traps for 40 meters that are narrower (but, longer is OK) than the ones I've seen in the articles. (A thought I had was perhaps using RG-174 instead of RG-58 ... these will be used at low power only, 10 watts max) High Q and narrow bandwidth is OK. These traps only have to resonate at one specific frequency. Any thoughts or advice? Thanks... |
