Брал из-за размеров. На 99 процентов использую на 70 см. Посмотрим, какова антенна на практике.

Took it because of the size. I use it 99 percent of the time at 70 cm. Let's see how the antenna performs in practice.

Honest 144/433 ranges, SWR on 2m around 3 during transmission, I allow measurement errors, measuring such an antenna is problematic on nanovna. There is also a third resonance in the area of 800-900 MHz, but I do not need it. Overall, the antenna is better than the burnt diamond on our marketplaces, it weighs 2 times heavier, has a whole circuit inside, not just a spring like there. I checked with a thermal imager, during a 30-second transmission, the antenna heats up at the top from 25 to 36 degrees, so be careful during intensive operation at the frequency.

Честные 144/433 диапазоны, КСВ на 2м около 3 передача идёт, допускаю погрешность измерения, померить такую антенну проблематично на nanovna. Есть еще третий резонанс в районе 800-900мгц, но мне он не нужен. В целом антенна лучше палёных diamond на наших маркетплейсах, весит в 2 раза тяжелее, внутри целая схема, а не просто пружина как там. Проверил тепловизором, при 30 секундной передачи антенна греется в верхней части с 25 до 36 градусов, поэтому осторожнее при интенсивной работе на частоте.
