Here is a video that I made testing out the Tram 1180 dual band 2m/70cm antenna. I am transmitting on the Yaesu FTM-400 xdr and reading vswr and output power on the surecom sw-102. Many hams have already expressed their negative feelings on the sw-102, but it is all I have at this time. Some club members have offered to help me with a comparison test video, which will verify the sw-102's accuracy. Look for that video in the coming weeks. Initial testing has shown the tram 1180 to have consistent power and swr throughout both bands. Power output is 40-46 watts, slightly lower that the Yaesu's advertised 50 watts. My Larsen 2/70 was performing very well on 70cm with high power and low swr, but lacked consistency on the 2m band. I will keep the tram in place for now, and the Larsen will be used for a future 70cm application. I purchased the tram 1180 new on ebay for $24 with free shipping. It is also available on amazon for a few bucks more. Keep in mind that this is an initial test, and I will make an update video comparing the long term reliability and performance. Feel free to ask questions or suggestions.
