Both LNR transformers have more insertion loss than MyAntennas.com MEF-330-1K you have... if you give it a try it will show less difference. More likely like 0.6dB instead 1.6dB with small LNR transformer.

Very nice article, I have a commercial EFHW antenna for 2M like you have analyzed. An interesting fact is that Dr. Best was my job interviewer and I also learned a lot from him too. He was very supportive of my "weird" antenna designs at Cushcraft Corp. some 20+ years ago. Keep up the great work...73 Danny Horvat, E73M aka MyAntennas.com
