can you use tv coax for 10 /11.meters please help the rookie
 

i wont to build a dipole ant for 10 meters can i use tv coax .or do i
need to use rg.58

Yes,
Ian.

Sure. The aluminum used for the shield isn't easy to solder
to, but 'TV' coax should work okay.

Yes, you can use 5 ohm tv coax but you will be better off using 50 ohm
rg 8 or rg 58 cable as the output circuit of your radio is optimized for
the 50 ohm cable. There is aloss of power in the mismatched cable. Not
much but it is there.
If you must use 75 ohm cable then investigate using a matching section
of 50 ohm cable.

Electrically, the tv coax should work nearly as well as rg58.

Only problem I see is the foil inner shield in tv coax might be
trickier to solder to a standard pl-259 plug that you will screw onto
your transceiver. The connectors they used to attach to a tv input
won't fit your transceiver.

i should came here in the first place the folks in the cb group
said tv coax will cause damage to my radio ,thanks 73s

What callsign do you use on 10m?

73,
Chip N1IR

yep, you can use it.

Your First problem is that you went to a CB group to ask that kind of
question. What were you thinking? You will have to match the antenna
to bring the feed down to 50 ohms. With a properly matched antenna you
should get the full 4 watt legal limit on 11 meters.

Note too the dipole will need to be slightly shorter to use on 10m than on
11m, but you probably knew that already.

There are addapters for F plug to PL259. I can hear it now, "oh my god, you
will loose at least a milionth of a watt if you use an adapter. That is
totaly unacceptable".

Probably the same one he uses on 20.

I connect to rg6 usinf an F to TNC adapter and then use a TNC to N adapter

Cut it for a multiple of 1/2 wavelengths.... Use type "f" connectors
and adaptors to uhf or whatever you want to use....

When the transmission line is cut for a multiple of 1/2 wavelength for a
particular frequency, you can put 100 ohms at one end and it will see
the exact impedance at the other end....

I use it on a 40/20 meter cross dipole and it works great and has very
low loss...
