Does anyone know where I can get a ready made good antenna in Mumbai? I know it is a very classical/obsolate subject. I live in Colaba, so do not need a high gain one. Space outside flat is a problem, so need a small outdoor type. At present made a type
4 and is not up to the mark I want. Thinking of making one but not have much time.

Thanks

Thanks Mahesh! I did make a J-pole antenna sometime back and it is working well. Someone from Pune in the hifivision forum suggested and I found the design online.
It was fun doing it...

Roushon.

Default Lubricant!

Urgently need very good quality dry lubricant to grease
the laser assembly of the cd player. Found out one of the
following is needed: 1. Molylube dry lubricant, 2. Krytox
glp-204 or 3. Silicon grease. Not sure which one is best
(may be all are same, I do not know) and where do I find
it in Mumbai. Any suggestion?

Every incidence is a learning experience!

Thanks and regards
Roushon.

I'm not sure about the quality part, I bought it from Lamington street(called White grease) for Rs15 from Suman 02223864117(stall nr Skyking). Works well for my DVDRW.

Found out, `white grease' is for heat sink. `Silicon grease' is different and is a lubricant, available in `Anupam Tools' exactly opposite the Police station on the Lamington Road. Sorry, do not have their phone number.

Anyway, thanks for the hint!

You better not use silicon grease. It is originally intended for use on O'rings in water tight containers.
I am very much sure of one thing...the local made Si grease will harden over time and u will have problems. Product from Dow Corning is good... don't know if it is still available or available locally.

As used for heat sinks , silicon grease is mixed with a white metal oxide filler. The one for lubrication generally is transparent.
The white silicone grease does dry out over time but that is in years and not months. If you do pull out anything after a long time which has grease under it you will have to reapply fresh grease while putting it back. Make sure you clean off the old grease before applying fresh grease.
