If you need antenna for another frequency band please let us know. Info about 2.4GHz and 5.8GHz antennas available on request.

Important: Due to large size and irregular shape of these packages the website often gets shipping cost wrong. Also sometimes we have to use wooden case which adds about 100 euro to the cost of antenna. For exact shipping cost please contact our sales department, be sure to give them your exact address and they will quote you shipping.

推薦配件： 我們推薦 AA-600 antenna analyzer 用於檢查天線的 SWR。可以購買接地套件 這裡，它們確保防雷。它們應安裝在天線處（如果需要，大多數偶極子無論如何都會接地）、塔基和發射機大樓的入口處。還使用 自封膠帶 which turns into rubber and protects moisture from entering your antenna system.
