If the radial system is less than ideal—due to short radials, too-few radials or poor soil conductivity—the antenna system will try to use the feedline shield as part of the radial system. This leads to a loss in the eff iciency and a higher take-off angle. Oft en the current introduced on the shield of the feedline causes RFI at the operator position. Placing a vertical feedline current choke VFCC at the base of the quarter-wave antenna forces the currents to equalize between the vertical section and the radial system, even if the radial system is less than ideal. The balanced terminals of the VFCC should be connected directly to the base of the antenna and radial plate with appropriate lengths of low-inductance tinned copper braid or copper strap.

Common Balun Applications

 Коммандер. Хейл очень опасен. Он… Но Стратмор растворился в темноте. Сьюзан поспешила за ним, пытаясь увидеть его силуэт. Коммандер обогнул ТРАНСТЕКСТ и, приблизившись к люку, заглянул в бурлящую, окутанную паром бездну. Молча обернулся, бросил взгляд на погруженную во тьму шифровалку и, нагнувшись приподнял тяжелую крышку люка. Она описала дугу и, когда он отпустил руку, с грохотом закрыла люк.

И закрыла .

Он сказал, что выгравированные буквы выглядят так, будто кошка прошлась по клавишам пишущей машинки. - Коммандер, не думаете же вы… - Сьюзан расхохоталась. Но Стратмор не дал ей договорить. - Сьюзан, это же абсолютно ясно.

North Dakota. Северная Дакота. - Северная Дакота.

Наконец он заговорил - спокойно, тихо и даже печально: - Нет, Грег, извини. Я не могу тебя отпустить. Хейл даже замер от неожиданности. - Что. - Я вызываю агентов безопасности.

Кровь из ноздрей капала прямо на нее, и она вся была перепачкана. Она чувствовала, как к ее горлу подступает тошнота. Его руки двигались по ее груди. Сьюзан ничего не чувствовала. Неужели он ее трогает.
