A trip to the plumbing department of the local Home Depot produced some PVC fittings and rubber booths to seal the ends of the conduit and create a feed-thru for the cables. I later used electrical tape and self-fusing silicone tape to seal air-tight around the cable. Green PVC tape was used to dress the conduit for decorative purpose. The 12 wire control cable is spliced in 3 - each one is a 4-wire cable section - one with the weather-proof connector for the antenna, one with the 4 wire lugs for the 80 meter coil and one for future use.

This picture shows also the concrete form tube - buried about 2 feet in the ground. Some gravel is placed on the bottom to help the drainage.
