Клуб радиолюбителей R4C

Радиолюбитель из Болгарии предлагает вариант антенны на диапазон 50 мГц. Антенна представляет собой четыре круглых элемента.
Входное сопротивление 240-300 Ом. Антенна имеет усиление вперед 10-12 Дб.
Подавление фронт-тыл 14 Дб. Все элементы выполнены из алюминиевого прутка или трубки диаметром 16 мм.

Размеры и внешний вид антенны на 50 мГц представлен на рисунках.
