Default Another Rx aerial length question

I've read through as many posts as I could find on rx aerial length, but still couldn't find what I am looking for, so I thought I would ask.
I have just bought a GWS micro receiver and it came with a very short aerial (about 30 cms or 1 foot). All my other receivers have an aerial about a meter long. Will the range of this micro receiver be reduced because of this short aerial? It is on 72.75MHz. I have seen threads that say for a particular frequency, you should have an aerial of a particular length, which is about 39-40 inches for 72 MHz. Does this apply to my micro receiver as well? I bought it second hand, so I don't know if the previous owner shortened it or not.

- That is a sort range receiver for park flyers and indoor use . Your question may be answered better if placed on GWS Forum if not answered on GWS Micro RX fact sheet Q4. "4.RECEIVER ANTENNA: Do not alter the length of antenna (50cm/19in) or coil it as range will be reduced. Always carry out a range check prior to flight. Always ensure the receiver antenna is positioned securely and safely in your model."
Information under "Antenna - Rubber Duckie, Micro & Whip Flywire - replace long aerials with loaded base antenna" and other information under "Radio Systems, Accessories, Alterations and FAQ" on my web page may also assist.

It's been awhile since I looked at these small rx's so my memory may be off, but IIRC the listed range on those is 500 feet which I did not think was adequate for the type of foamy I wanted to use it on...

That information would seem to agree with Alan's response and could very easily explain why the antenna is short compared to full range rx's.
