Re: newbee here...just made the order...antenna question on old G5RV
I've heard good things about the G5RV.toggle quoted messageShow quoted text
Never had one.
Since you got one up, I suggest you go ahead and use it.
It is resonant on 20m, will give a 50 ohm match there if the ladder line is cut to the correct length.
I would recommend at least borrowing an SWR meter to determine
over what range of frequencies it gives a reasonable match.
For multiband use on the G5RV you do need a transmatch of some sort, but it could be cobbled together cheaply.
Ladder line has much less loss than coax even at high SWR, so a transmatch between the ladder line and the coax
can make this an efficient multiband antenna system.
Ralph's off-center fed dipole can be easier to put up than a center fed dipole, but does require a transmatch.
The end-fed is an extreme case, I have one of these:
That particular EFHW is done well, is a good radiator, and with the matchbox provided can give
a good 50 ohm match across most of the HF ham bands with no tuner.
I would still recommend having an SWR meter to determine if things are working properly.
If you might have ice loading in the winter then going to heavier antenna wire is a good idea,
buy the MEF-330-1k matchbox and the 14 gauge antenna wire separately:

With almost any antenna designed to work over a large frequency range you will need a tuner of some sort. Either a built in one or external.
