New quad antenna project
I am working on building a new antenna. It is based on this design, which uses a mix of PVC pipes and fiberglass rods, except I adapt it to a 20m antenna and replace the PVC with aluminium for solidity. It should be possible to take the antenna apart and rebuild it if necessary.

|guy rope||2x100'||hardware store||?||63.98$||to secure the mast, using poplypropylene/nylon rope, each line should support around 300lbs of pressure, enough for the 500lbs of pressure with a 90mph wind||Antenna and accessories||Part||Amount||Where||Weight||Price||Notes|

Total planned price: ~373.77$
Total planned weight: ~25lbs++ - not including 180lbs of sandbags, the pole and tripod.
- Gauge: 10-16 AWG is okay (see AWG, that is 1.2-2.5mm or 1/10" - 1/20"), and can be insulated, according to this page
- Using welding wire is a good idea, as the lightning bolt quad uses
- I was suggested Dubo for electric supplies
Waiting for parts to be shipped and for the rain to stop.
Those parts were considered during the design phase but were discarded for various reasons.
|welding wire aluminium||270' spool||canadian tire?||?||example: Aluminium 5356 MIG alloy - too hard to find|
||1||home depot||?||according to Rick, this could create interference|
||2||creativeshelters.com||3.08$||couldn't order, they don't accept canadian zip codes, and shipping is 30$ anyways, and I don't trust PVC|
||8||home depot||~5$||we'll use tie-wraps instead for spreader/wire attachment|
||4||home depot||?||PVC pipes are too flexible to hold properly, we need fiberglass|
||44.4m||???||29.32$ (addison?) 48.64$ pour 2x12 22m (dubo)|| |
I had a lot of problems finding proper parts (pipes, raw materials like wiring and so on) in Montreal, which made building the antenna quite tricky, as a lot of things needed to be ordered online, which raised the overall costs because of shipping.
Je collecte ici des bons sites au sujet du ham radio.
- Manuals, courses
- hardware guide - motorola
- Other documentation
This needs to be merged into Software
- the oracles
- http://packages.debian.org/minimuf - allows you to compute the WikiPedia:MUF depending on salar activity and so on, but has an unusuable interface (you need to enter a series of digits... how about a GUI?!)
- http://packages.debian.org/gcb - calculates the right angle for your antenna
- http://packages.debian.org/xplanet - can show azimuthal projections of the earth on your background, screensaver or window - I use this in myxsession:
xplanet -latitude 45.5 -longitude -73.66 -wait 60 -label -projection azimuthal -fork -radius 90
- testing tools
- http://packages.debian.org/ibp - very useful for training to receive distant comms: show you which beacon is active when, with a map
- to be tested:
... others to follow, there's a whole hamradio section in debian.
Stuff to buy next
- VHF/UHF SWR meter
- Baofeng UV-3R MKII radio (<50$) avec cable de prog ou UV-5R
- 100' of RG8 cabling
- Another HF radio?
