To measure the antenna and feedline 'system', disconnect the antenna
feedline from the receiver and connect the end of the feedline to the VNA.
You can not make a credible measurement of the antenna/feedline 'system'
with the preamplifier connected to the feedline.

Hi,
I was thinking about this DC Blocks.
If I understand correctly those DC Block block the DC current and without
DC current my Low Noise Amplifier does not work, correct ?
So if that is the case, why not just turn Bias Tee OFF and I can measure
through ... right ?
BTW I ordered the pack of two. For what do I need them if above is OK ?
