Wire roughed in. 108' of cable used. Wow. Insulating soon hopefully tomorrow night. Found a great solution in Canada for those wanting 703 but cant find it. Use Knauf 2.25 PCF insulation board. Product 5003355. 60$ a case locally. Will report on its work ability soon.

If you wanna build broadband panels use foil facing wall. If you wanna build lower frequency concentrated panels face foil into room. Using foil facing wall dramatically reduces effectiveness at low frequencies (by 1/2 or so). If you wanna build 4" super panels use 2 stacked with foil in middle. Better than safe and sound but more depth and $.

They look blue and cold. Poor things. Need insulation.
