Title: Antenna coax too short! Extension OK?
Post by: KD5ZVV on December 11, 2003, 09:22:06 PM
My antenna coax isn't long enough to allow me to mount my 5/8 wave mag mount antenna in the center of the roof on my supercab Ranger.  Is there any downside to adding a prefab 5 foot piece of coax to extend the antenna feed so it will reach?  Thanks!

No.

You are most likely working with RG 58 right?
What came with the antenna is probably 10-15 feet so another 5 won't really kill ya (power loss wise).

Going 40-50 feet (VHF UHF) with that stuff is another story.
Naturally,in HF it's no big deal though.

Start at the mount, and install a new piece of coax, that is long enough. Extension cords (if you will) are no good. While you're at it, use some good coax in its place. While RG-58 is already lossy at VHF and above, adding connectors and couplers only adds to the losses, not a good idea.
