I need to make exact copies of some LTO 4 tapes, but I'm not sure how to do this.

Here is some info regarding my system:
OS = RHEL 6.2
3GHz Quad Core Processor
8GB Memory
One External SAS LTO 5 tape drive

Should I backup from the source tape to a tar file on the hard drive, install blank tape and then extract the tar file to the blank tape? What is the best method?

It depends on how the tape was created.   You have to worry about blocking factor and tape markers.

example, they could have done a dd if=nameoftarfile  of=/dev/rmt  bs=10k  to force a blocking factor.   Or the tape could have been built with dd and cpio, or neither.

It is semantics, but you don't want a copy of the tape as much as a copy of the usable data.

So if it was me, I would use whatever utility you used to create the tape to extract it into a scratch directory, then build a new tape using that same software and the scratch directory full of data as the source.

Make sure that when you extract the data you don't overwrite anything ;)
