[Hackrf-dev] Antennas, Cables and Connectors [Important Questions on RF Performance]

[Hugh Blemings]

Hi Sohil,

Just to pick up on one point in your email;

> Q1. Is there any difference between using item 8 and 9 on this list with
> the LPA Antenna.

As has already been pointed out, there is no significant difference with 
these two connectors electrically.

However the right angle connector, if you face it back down the length 
of the PCB when you solder it in, will make it easier to route the 
feedline in such a way as to minimise the affect on the antenna's 
performance.

As I understand it, it's preferable to have the coax run towards the 
back of the antenna and as close as possible to the PCB to minimise the 
change in the antennas pattern.

Good luck with your SDR endeavours!
