You can use the grounding kits, which are very effective although they 
do require some work and weatherproofing.  There is also the simple way, 
but expensive. Two coax connectors and a bulk head connector.

I'd use the bulkhead connector with less expensive coax on HF.  All 3 
connectors cost less than one hard line connector and about the same as 
1 grounding kit. They are also very effective.   I use it up through LMR-600
