Review on GRA-1899T Multiband Handheld Portable Telescopic Antenna | QRP for YAESU FT-817/FT-817ND/FT-818/FT-857D, ICOM IC-705, MFJ X5105, KX3 | VHF/HF (80m-6m) 3.5-50MHz | BNC by Kyle Robinson

Conclusion: It works. Line above: What a headache. It looks like it, but it's not an MFJ 1899T antenna (and that might be fine). I tested it at 80 and 40 meters. I used the formula from the mfj 1899t documentation for the length of the counterweights (180/frequency) and it worked. However, antenna length was an inch shorter than documentation for both the mfj and packed sheet (at 80 m and 40 m). Something different. Therefore, you CANNOT use this antenna without being able to adjust it. My radio has a built in SWR plotter. At 80 m, the bandwidth was only about 50 MHz. Even with an SWR plotter I had to look for resonance and then slowly adjust the length of the antenna to my desired frequency. I suppose it would be fine if you stopped at a frequency and called CQ or a rag, but I couldn't see how to use that to check for contacts. So far I haven't had any contact at 80 meters. 40 meters was like day and night. 40 still required careful tuning, but I was able to tune it in the mid-range with an SWR of less than 3 at each end. I made good contacts for 400 and 500 miles in a matter of minutes. I want a small and light 40m camping antenna and I think this antenna is for you. My final rating is 5 stars minus one. It makes excellent contacts, but QSY is difficult to set up and use, especially when changing bands. Hope that helps! - aa2mz
