Heliax LDF1-50A
Heliax LDF1-50A adalah kabel koaksial berkualitas tinggi untuk mendukung sistem komunikasi frekuensi tinggi dengan performa optimal. Kabel antena ini adalah bagian dari seri HELIAX® yang dikenal luas karena daya tahan dan efisiensinya dalam transmisi sinyal.
Kabel antena repeater heliax ini menggunakan bahan dielektrik busa polietilena (foam PE) yang berfungsi sebagai isolator antara konduktor dalam dan luar serta membantu meminimalisir redaman sinyal. Bagian pelindung luar dibuat dari bahan polietilena (PE) yang tahan di berbagai kondisi.
Konduktor dalam kabel original Andrew ini terbuat dari kawat aluminium berlapis tembaga (copper clad aluminum wire). Sementara itu, konduktor luar menggunakan tembaga bergelombang (corrugated copper) yang memberikan kemudahan dan perlindungan elektromagnetik.
