So what is the easy reliable cheap method to get the job done?

The only methods I know of are some form of crimp. Many variations of RG6 and RG11 with Al shields are widely used in the CATV industry. "SnapNSeal" is a widely used brand of Type F connectors that come in different physical sizes to fit those different cables, and there are crimpers to go with them. I've used these RG6 cables for receive antennas for more than 40 years. On one of my gigs almost 50 years ago, I installed a lot of MATV outlets in Sears Tower and in apartment buildings on Lake Shore Drive when they were under construction.

The only Al shielded cable I'm using for transmitting is some vintage 1/2-in CATV hard line that I inherited from a neighbor SK. That hard line has Cu-clad Al center and Al shield. I'm using sections of it for parts of the run to two mono-banders. There are photos and text of page 6 of showing the method I used. Where I used braid, other hams have slit copper tubing in half lengthwise, and are also listed on that page.
