quad RG6 vs RG59 coax cables for TV antenna and Foxtel

We use RG6 Quad shielded Coaxial cable for free to air TV antenna and Foxtel installations and extensions. Despite common belief RG59 might be a better alternative for some antenna installations.

Based on the specifications, the differences between the cables in terms of antenna signal are minimal, especially for applications in the Sydney Northern Beaches area where TV stations operate on frequencies ranging from 150 to 650 MHz. Additionally, RG59 reduces interference from mobile networks above TV frequencies without requiring extra filters. RG6 is typically designed with water and UV protection, unlike RG59. However, RG59 is thinner in diameter compared to RG6, making it a suitable option for indoor TV antenna extensions, narrow spaces such as under carpets, where RG6 may not fit. Therefore, RG59 is a preferred cable for indoor antennas and fly leads available at electronic stores, as long as the cable length does not exceed 20 metres and it is not used for Foxtel or UHF antennas.

RG6 and RG59 cost from 40 cents to $1 per metre depending on how much you buy.

If replacing the TV cable improves reception but not wholly, the problem likely stems from the antenna, which requires servicing or adjustment to optimize TV signal reception. With the TV antenna operating perfectly, there should be no difference in the type of cable connecting the antenna from the wall to the TV. If issues persist, we can realign, repair, or replace the antenna system for continuous TV reception.
