That choke is probably too small and will change SWR, but thankfully reactance in reactances does not dissipate power. Reactance simply stores and returns energy. 226 ohms of resistance would be about 330 watts of heat at 1500 watts into 50 ohms (about 273 volts RMS). To find the heat, we would need to know inductor Q. If Q was 1, it would be 330 watts. A pure reactance is zero heat. Odds are the inductor Q would be in the hundreds, so dissipation would be negligible. 73 Tom _______________________________________________ UR RST IS ... ... ..9 QSB QSB - hw? BK
