Nothing wrong with that for a misfire alley or even a torture racklaunch range.

Jerry,
What is the torture-rack launch range?
Thanks, Patrick - some of my rockets have Evil Twins!!!
G Harry Stine, founder of NAR and author of the bible of model rocketry (hereafter referred to as "GOD"), "The Handbook of Model Rocketry" recommended this format:

Tripoli and NAR typically use a centrally controlled range set-up in principal like this at group launches. A "Torture Rack" refers to the fact you have to wait till every rocket is ready to launch the first one and you have to wait till the last rocket is launched or misfired to recycle the pads. The bigger the launch the longer the wait. At LDRS launches I have attended, average wait time is 2 hours, and 4 hours is fairly common.

It is interesting to see the total void of logic and reason applied to TRA offset distances as well. Real brain surgeons and rocket scientists, these ones are :)

Rack is great for a football halftime show or retail store flight demo where the whole purpose is to sequence the rockets with the narration or the music, but for a group launch with hundreds of heterogenous rockets, misfire alley is the ONLY way to go and allows use of your own pad. In fact encourages it.
It is important to note that TRA and NAR have refused to release torture racks from their cold dead fingers for the past 10 years. Learning disabilities extreme.

So in all but one or two sites it would be perfect then. And so the exception can be either a directional antenna or someone with a HAM license. Seems reasonable to me, especially if you are just making one for yourself and not making them commercially.
And if you are making them commercially then the antenna would be an added income for you.

Yeah, I guess. I never thought of it *that* way... :-)
Good point - since this *is* only supposed to be a 'one-of' type thing. But... if I can spark enough interest in it, I might be tempted to go into custom-built thing for clubs.
Len, Make the controll end and leave the wireless transmission to their discression. Give ideas like short range linx gear or more pricy stuff.
TX/RX is easy if you have the gear to feed it the signals.
I'd do that anyway. :-) But if I do it that way, I'd like to be sure that I offer suggestions that *work*... and that means testing them out myself first.
... and if the data isn't "reconstructed" into some other format. ;-)
