Hi All

I'm getting to the finishing stages of building my Merkava BAZ 3 and want to add an ariel to the turret but I've no idea of the length to use.

Does anyone know of the correct length in 1/35 or if not is there a general rule of thumb to use?

It appears modern 'whiplash' aeriels are longer than the WW2 aeriels used but a guide to either would be helpful.

Thanks

Chris

This area is quite substantial in terms of length of aerial, but also if it's a rigid, whip, straight, or tapering aerial.

I have been moving over to modern AFV modelling in the last 18 months, and I'm still trying to work out the specifications for the different types of aerial.

I'm as curious as you are regard this.

I'm unfamiliar w/that type, but most photos I've seen of IDF show flexible antennae built up in sections depending on radio requirements. Refer to photos of your type and look for how many sections of each antenna. They are usually painted white, so the sections are visible. I guessed how long the sections were on my IDF efforts. Usually there is a rack of sections somewhere on the vehicle to give you a hint on length. Hard antennae were short fixed length (like sensors, GPS, etc.) or extensible (long range), these could be up to 40' I think. HTH. PaulE

Hi,

Simon, Paul - if you guys aren't sure then I guess the best thing to do is 'guesstimate' it thanks.

Jimbo - he, he, snigger...

I was wondering when the wheels were going to fall off this thread.

I blame Jimbo, with Smith as a willing accomplice

Well it seems that they use a Tadiron VRC-120 comms system

LINK

According to the spec it is VHF 30-88Mhz

Now this lot LINK make this military spec whip aerial that operates at 30-80Mhz VHF

I think it is a fair assumption that these aerials are fairly similar for a given performance spec so 2400mm would be a good guess

Just my best guess of course as I can't find any specific detail for actual IDF aerials

Thanks Simon, so.oo...If I divide 2400 by 35 (for 1/35 scale) it works out at 68.5 mm or 2.69 inches (2 5/8" or thereabouts for those of us of a certain age).

Can it be that easy? Sounds about right tho..🤔

And holding a tape measure on top of the aerial mounting, it looks about right too...

I think I'll give this a try when I get my bench time next week.

Thanks for the help,

Chris
