Its aerial time again.
I’m pushed for construction time these days.
For VHF it might be a vertical dipole.
Instead of buying bits to make one, how about buying one for FM VHF-Band II and adjusting the length?

Any thoughts welcome.
Price of the bits to make one come to over £30.
If we have success (ie cadet interest) with the new ‘base station’ more directivity a HB9CV might go in if the dipole doesn’t make it to the tango.
How much more exciting does it get!
if you are going to the effort of buying an aerial for dedicated VHF work why not buy one intended for the job?
i have just purchased a Diamond BC-101 (]url=http://www.hamradio.co.uk/aerials-antenna-manufacturers-diamond-antennas/diamond/diamond-bc-101-pd-2523.php]Martin Lynuch & Sons[/url]
and will need 100mm off the top to be central to the most commonly used Victor frequencies we use.
i would have thought making one would be a better option for the sense of achievement but really can’t see the benefit of buying something which isnt intended for the intended purpose
If you’re looking to buy bespoke antennas, I can highly recommend Sandpiper Aerials. I’ve used them a couple of times and they did a particularly good yagi antenna which the Sqn used to fire in to the ‘London Project’. Just tell them what you want and they’ll make it for you!
i have to recommend them too! never used myself but i know of two other Sqns in the Wing, plus the Wing’s kit which has been supplied by Sandpiper and always hear good things
Thanks for the suggestions.
5/8 wave - never thought of that.
Have always installed J-poles or slim-jims - no ground plane needed.
If we want to get into the Tango from our ‘less than favourable’ location it might be just what I’m looking for.
Update time.
The project has been revised so that the antenna and mast must be temporary for parade nights and stowed in between.
So for being robust it will be the dipole for the time being.
Next update;
Antenna is now resonant and seemingly able to access the Tango on low-power.
At least from ‘the secret antenna test site’, which if you press the secret button quickly turns back into my back garden.
Used the analyser on this one - less hassle.
