View Full Version : Antenna 2M question
08-01-2012, 10:26 AM
I've been using my Yaesu FT-2900R as a base station with a N9TAX Slim Jim. I currently have it on a painters pole which is about 16" total. I have the painters pole stuck in a huge traffic cone which keeps it uprright.
Anyway, I'm looking to throw something up on the roof. I'm wondering if I should just mount the Slim Jim up there on a bow made of PVC or if I should get something else. The Slim Jim is omnidirectional. For working repeaters is it better to get a directional? I was looking at the Elk 5-element one for example. Would I be able to hit repeaters on Cheyenne Mtn and Pikes Peak without moving the directional or would I have to put it on some kind of antenna rotator?
Here's the Arrow J-pole (http://www.arrowantennas.com/osj/j-pole.html) I have up near the top of my roofline. Works great. I have the 146/440 version, naturally.

Or make your own, learn and save some $$. For me, half the fun is learning about and building antennas. Here a couple of links for j-poles. With a j-pole and 5 watts you should be able to hit any repeater in the Springs area including Pikes Peak. Here are a few links to home brew j-poles.
Recently built my first HF antenna and now looking into doing a "portable" 6m sometime soon.

can you hit the repeaters without the antenna mounted up high? Are you looking for more range?
I made a copper pipe j pole and it works well for me but I kinda tested my range with a smaller antenna and lower wattage first. I knew it'd be a slam dunk.
If you can't touch a repeater with what you have now you might need something like a yagi.... If it kinda works, then maybe a slightly better omni directional antenna mounted up high will work.

I can hit repeaters pretty well in the Springs. I'd just like to extend the range. My house is up on a bit of a hill, so I think if I put something up there I'll be in good shape. I just didn't know if I should throw the Slim Jim up or get something else.
I was looking at some homebrew stuff last night, I'll check out those links posted here.

Then you'd probably be fine just getting what you have up a bit higher...
The only thing that looks kinda funky with the slim jim is that it may get rocked by the wind. It seems like it flap around a lot.
That may be a reason to make a nice sturdy J-Pole for the top of the house, then keep the slim jim for other stuff where you may be travelling and want a packable antenna.

I think I'll just use the Slim Jim & make something like this to keep it from moving:
I have a second one rolled up for portable operating.
