I think you will find the length (height) of the antenna on a MV depends on the radio fitted. The antenna is "tuned" to the frequency of the radio set. For example; A U.S. RT-68 radio uses a shorter 2 section antenna than the 3 section one on a RT-66 or RT-67 radio even though the RT's look identical. It is the difference in the band width that determines the antenna sections used. RT-68 (38 to 54.9 mc.) uses 1 MS-117-A and 1 AB-24-GR antenna sections. RT-66 (20 to 27.9mc) and RT-67 (27 to 38.9mc) radios use 1 MS-116-A, 1 MS-117-A and 1 MS-118-A sections.
The RT-66 is used by armor units, the RT-67 by artillery units and the RT-68 by the infantry.
The British/Canadian radios such as the C-42, C-45, C-12 and No. 19 sets will also have their antenna "tuned" to the frequency of the particular set.
On the C-42 set (36 to 60mc) the proper length for the antenna is 8 foot high (use two 4 foot ant.sections). The manual states "A longer or shorter aerial must NOT be used". The C-42 set is most often found in armoured vehicles and infantry unit MV's.
The C-45 set (23 to 38mc) is most often used by the Royal Artillery MV's such as the Abbott SP Gun. This set also uses the 2 section 8 foot aerial.
The C-12 radio set will use a 3 section 12 foot aerial when used in MV's F.F.W. as will the earlier No.19 set although an 8 foot one may also be used.
Note that some Ferrets and the like (Canadian for example) later used U.S. radios with their corresponding antenna.
If you plan to actually use your radio, it is important to make sure you are using the correct antenna, not just one that "looks cool". Never, never, transmit on your RT without having an antenna hooked up as you WILL burn out your transmitter. And don't hold on to the antenna when transmitting.....could be quite shocking!
As I am only a R.K.I. (Reasonably Knowledgeable Individual) on the subject of MV radios, others on this list may expound further on this.
