[Antennas] Joining Feed Lines

[Kevin Nathan]

Hi All,

It's been a while since I've dealt with this and I just don't remember the
answer.  I need to move two antennas from a rooftop tripod to my tower.
They have been fed with approximately 70 feet of RG8 each.  One of them is a
2 meter/70 centimeter collinear and the other is a six meter three element
yogi.  How much would I lose going through connectors and a barrel which
would allow me to use RG8 lengths I already have as opposed to the expense
of new single runs of cable for each.

I'm not looking for a debate here, just some consensus as to what I might
lose before I take a run to the radio store tomorrow.

thanks much all and 73.
Kevin, K7RX :)
