A G5RV is really an inefficient collinear antenna, so it needs to be a
flatop, not a Vee or L. Model it and you will see it is a 'long' (on 20
meters) Extended Double Zepp. The extra length improves the pattern into
multiple lobes at the cost of some gain. A true EDZ has more gain, but only
one very narrow broadside lobe off each side. The G5RV has 3 lobes off each
side.

I've had poor luck even using the G5RV as an inverter V.

Guy. My best option is to install a G5VR but having one half bend back
90
degrees horizontally so that when you look down from the top it is L
shaped.
My question is, will this degrade performance very much and in what
way.
Many thanks and regards,

Need more information: How high is the antenna, what type of
transmission
line do you plan on using, and what frequencies will it be used on?

Bending the antenna will reduce the real part of the input impedance,
thus
increasing transmission line losses. It will also tend to increase its
directivity in the direction of the "vee".

The G5RV antenna tends to exhibit higher transmission line losses. See
the
extensive analysis at www.vk1od.net

Suggest you obtain the free download of EZNEC from www.eznec.com then you
can analyze the antenna for yourself. Also there are many free programs
available for transmission line analysis. Probably Reg (G4FGQ) has one
for
free.
