The modulator wants to see a 75Ω load, not some random match through a crappy matching transformer. This is why you need several feet of RG6 or 59.
All the radio guys know antenna is everything. Connect some random antenna to just about any transmitter over a few watts and the final transistors will instantly short. These modulators are fairly robust, but the hybrid package they use for a final is not feasibly replaced. If it fails best to buy a whole new mod

It looks like I'll be constructing an antenna today. I don't have an antenna analyzer so I'll go with the 42" recommendation and make my leads exactly the same length. I can use whatever length of RG6 so what would be recommended? Is there anything else that I can do to aid in success without the need for equipment that I don't have?
