Before you invest to much more time and money in your project, no matter
how necessary it may be, you need to look at the signal loss generated
by the RG174 you are proposing to use. It is so extreme only very short
lengths should be used, 1" to 3'.


RG174 would be a very poor choice.

LMR195 (RG58 dimensions) is more likely to be the type of cable used for
small diameter, or larger LMR types for a long run like 40'.

The loss in 40' of LMR195 at 2400MHz is ~8dB, not a pretty picture. Losses
in a metre or three are practical.

Owen;

I just picked on RG 174 as an example. Your choice is not very much
better which only points out the problem with coax at high frequencies.
I think that the original writer has decided on his own to do something
else.
