Of course you realize that the antennas like the CR-8900A are tuned to the Ham Bands, and if you stray off frequency too far, they will not be resonant and cause a high SWR to the radio which can blow the final modules. So it is neccessary to have an antenna resonant to the frequency of desired operation, regardless of legality. Otherwise, if you blow the radio up, then you can put it on Ebay for Radio Mart to buy and re-sell as "Perfect mint Condition". The problem with that is some innocent buyer will get stuck with a radio that is hopeless cooked out! So if you are going to operate "out of band" which certainly isn't a good idea, but who am I to complain, be sure to use a MFJ antenna analyzer and adjust the antenna for correct resonance at the projected operating frequency. Good thing Riley retired! He wouldn't be happy about this at all.
