1  eHam Forums / Elmers / Help on setting up an HF antenna on: May 10, 2007, 07:20:04 AM
Thank you very much for everyone's inputs.

As a matter of fact, I have a B&W AP-10A antenna that I have used before for my HF work. The antenna did an OK job, but never gets me farther than the central plains. I  was running at 50W or even 75W but surprisingly I never got any RFI in my apartment or complaints from others. I was running SSB/PSK31/RTTY at those times.

I will look into the endfedz antenna, at first glance they seem to be too good to be true, but after I read the reviews, I am starting to give it a second thought now. Wink

Hello all,

It's been several years since I left the world of HF and I'm planning on getting back to the hobby. I live in a apartment that is about 40 feet above ground. I spoke with the management and they said rooftop access is no-no. So that basiclly leaves me in a situation where I have to install "stealthy" antenna..

I would like to run a dipole with one leg down from the window sill to the ground (40 feet) and the other leg loops around the room act as a counterpoise(prob 20 feet). I would like to get 20m but 40m would be even better.

I understand that the two legs won't be balanced, but is it possible to run both legs down the window? I've read elsewhere that separation is important when running both wires parallel and it's best to run it in a V configuration. The window is about 5 feet wide so that would be the maximum separation between the two legs.

Thank you,
Dennis

Does anyone have experiences with hamstick dipole? I live in a Apartment with restrictions too and I'm considering hamstick dipole might be the way to go for me on 40m
6  eHam Forums / VHF / UHF / 900 Mhz and 1.2G rig? on: February 15, 2004, 02:08:00 AM
Thanks a lot guys...at the price of around $200 transverter looks like to be the way to go for me!

7  eHam Forums / VHF / UHF / 900 Mhz and 1.2G rig? on: February 08, 2004, 04:42:30 PM
During the last VHF stations I heard other stations had 900 Mhz and 1.2 Ghz capability. I wonder what kidns of rig in the market that has FM/USB mode in these freq.

Also what are the choices of antenna and the cost of playing in the GHz range

Thanx es 73

8  eHam Forums / Computers And Software / 4NEC2 Antenna Modeling Software on: January 27, 2004, 12:15:05 AM
I tried it at one of my friend's house...it looks like to be a very powerful program to model antennas an dgives projections of your signal, but takes great effort to understand and get a hold of it...hihi
9  eHam Forums / VHF / UHF / aurora 2m on 1/25/04? on: January 26, 2004, 11:33:42 AM
I saw a report of aurora on one of the DX clusters and it was also from the "9" area.

Here's one site that may be helpful for you to identify the signal:
http://www.minecost.com/hamstuff/ (look towards to bottom)

or here: http://www.kolumbus.fi/oh5iy/msobs/vhfdxpro.htm

I worked in the contest too but this contest was not as much as excited as the one in June...hihi

11  eHam Forums / Company Reviews / alinco vs motorola on: January 23, 2004, 10:48:55 PM
I have the DJ596 HT and it's a great model for beginners. Some basic function may be a little inconvinent (ie. you need to press VOL then rotate the knob for changing volume) and stock antenna performs poorly on 2m. But other than that, it's a great little rig for begineers

Pros:
- BNC connector (would not break easily like SMA do)
- External DC power gives you 5W
- key up beep (personal favor..hihi)
- Alphanumeric

Cons:
- Inconvinent basic functions
- The stock antenna slips with the rubber cover for  mic connector (can be fixed if using a 3rd party antenna or removing the rubber cover)

For the Motorola, I wouldn't recommand it for the first radio...these radios need to be programmed externally using computers and RIB (Radio interface box). The cost of the radio may be as little as $100, but if you buy the original RIB by Motorola, the cables (for programming and interface), and the software...it can easily end up as many as $400 or more.

Motorola made excellent radios and honestly I want one myself too, but the cost is just too much for me

12  eHam Forums / Elmers / Good ground anchor for wire antenna on: January 12, 2004, 04:12:40 PM
Hello all,

As I stated in the previous posts, I'm planning to install a random dipole antenna in my room. I want to throw one end of the wire to the ground from my window (90 degrees to ensure "stealth") and the other end run inside my shack room as a counterpoise.

What should I use for the ground anchor that can endure reasonable amount of weathering (well at least snow and wind). My budget is very limited so any household items would be excellent.

Also If one leg of my wire is 50 feet and the other end (counterpoise) is about 30 feet, am I still able to tune it to 20m?

73,
Denny

Hi OM,

Does anyone owned this 2m/440 HT antenna before? How is the performance on 2m...

I'm currently looking for one that can replace my stock rubber duck that is useless on 2m...hihi ;-)

Thnx es 73

14  eHam Forums / Elmers / How good is a loop for HF? on: December 23, 2003, 09:33:36 PM
Thanks...I'll look into that half wavelength
15  eHam Forums / Elmers / How good is a loop for HF? on: December 23, 2003, 03:32:19 PM
Thanks for the input guys...

I figured out that my window is approx. 6 feet on each side, which results in 24 sq feet. I have to to admit that it isn't much.

Say if I have to run the wire with a total length of 1040/f (feet), can I run all the wires next to another to achieve full length?

Here's a drawing of question:
