David,
If you are anywhere near me (Aylesbury, so must be closer than Ferg!)) I'm happy
to turn out and provide some hands-on help if you think that would be useful.
I suffer from the delusion that I know a little about antennas (antennae?) and
I have a couple of suitable SWR meters and some practical experience messing
about with this sort of antenna. Please give me a call on 01296 689165 if you
think that would be any use or you just want some telephone advice.
Regards
Bill

Thanks for the offer but I am in South Manchester=2C nr airport!. But I may
ring you when I am next in the garage. Originally with the length at 490mm
as per drawing the best SWR was at 133.00. I shrortened it down to 480mm b
ut could not get best SWR mid frequency range. I have temporarly extended t
he antenna to try again.

David-
I think you have been trimming your copper tape in millimeters.=C2- I did
a couple of calculations this morning and you change resonant frequency is
about .38 inches (around 10 mm) per mhz.=C2- So--if you have been trimmi
ng your foil at 2 mm per check, you would need to trim it 5 times to move i
t 1 mhz.=C2- If you do your graph, you should be able to calculate very c
losely how you need to trim it and do it with a single cut.

| Subject: | Re: Wheel Pant Recommendations |
G'day Tony,
I'm building a Little Toot Sport Biplane and I'm using some custom Grove landing
gear with all grove brakes, axles, etc. It will have wheel pants. You can
see some pics in my "Taz" build gallery in the second URL in the signature block.
I don't know of any wheel pant mount that will go behind the landing gear.
I can understand wanting to do that. Cleaner, neater and probably less drag,
but it's tough to engineer. One benefit of the normal way is building jacking
pads which go on the inside of the axle. I'll have to add some pics of the
jack pads we use on the Toot later today. If you should like the wheel pants
we use on the Toot I'll put you in touch with Tommy Meyer (Tommy's dad,George
Meyer, built the first Meyer Special, Little Toot in 1954) If you should want
a set of those pants.

of wheel pants that look best for our beasts?? It is not a bad time to find
out before you bolt all the bits together, as there is a mounting bracket that
sits in behind the axle when bolted onto the leg.

me a surplus stage 1 Kit.

Dave-
Sorry, I can't tell you.=C2- It calculates to 43 inches, but I canabalize
d the included antenna and cut it for the amateur 2 meter band.=C2- It is
installed just aft of the "D" panel and cut for 146 MHZ.=C2- I used a co
mmercial (AAE) antenna for my comm.=C2- It gets a touch technical, but th
e AAE antenna is what is called a folded dipole, so it is about twice the b
andwidth of a conventional dipole.=C2- If you attempt to trim it, it will
destroy it, so you just put it in and away you go.=C2- I am at 1/1 in th
e center of the band and about 1.3 / 1 at the edges with it.=C2- If you w
ant to spend the money, the AAE antenna is a great choice.=C2- I also use
d one of theirs for my transponder.=C2- It is a flat tape, about 1.5 inch
es wide and glues to the stern post beautifully.=C2- It has a built in ba
lun, so all you do is=C2-attach your coaxial cable and glue it in.=C2-
No tuning or trimming.=C2- =C2-
