Base Antenna

Post by garys »

My Radio Shack version of the ST-2 broke during the spring. I was finally able to get up on the roof today to make a temporary fix, but it's still going to need replacement.

I'm looking for some thoughts on a suitable replacement since the ST-2 and RS version are no longer available. Well, they are, but the Ebay prices are silly.

One option is an Antenna Specialist MON -R31 that has been sitting in my basement for some years now. I have a couple of different AS whips that will fit on the base, including one of the one with the aluminum shell on the lower radiator of the mast. I always had good luck with AS scanner antennas.

I know a lot of people use Discones, but I wonder about the lightning strike issue that I've read about.

Any other thoughts? I'm not looking to spend hundreds of dollars, but would like something with reasonable performance.

Thanks,

Gary

If you do not need low band, the DPD Omni x is an option for a multi-band antenna. I use one with a Jim M75 pre-amp works well for me.

I only need low band for MSP, at least for the most part. I'll look at this antenna, but it's a bit more than I really want to spend.

I've been looking at the Hustler base discone DCX antenna. Seems like a decent option.

What are the lightning strike issues you have read? Just curious.

As I recall, there was some discussion a few years ago on RadioReference about a higher rate of lightning strikes on discone antennas than other styles. It's a vague recollection which is why I'm asking. Maybe someone can confirm or deny that.

I haven't looked on the Internet yet to see if there is any information on it yet.

I have had a Discone mounted off the side of my house for years, so far so good. Now watch, something bad will happen!

I've always found the discone to be a reliable workhorse. I'm not so interested in low band stuff so I haven't used the type with the added-on whip.

If you get one, go with the stainless steel Tram model that's readily available on eBay. Steer clear of any NOS Radio Shack discones (they use aluminum elements that tend to fracture with stress and fall off) and don't bother with the three or four element versions from other manufacturers.

Sturdy, functional.

Another vote for the American-made DPD Omni X. I've had mine up 12+ years with no issues. Dave is a pleasure to deal with and was also active over on RR, too.

Today's windstorm rebroke my repaired RS antenna. I'm going to replace it, probably on Sunday. I've decided to go with a Tram 1410 Discone. It got good reviews on Amazon and is very well built from my experience putting it together.

I'll have a whole winter to determine if it works well for my needs. If not, I'll look at other options come spring.

I got this up today. Just the normal install antenna on the roof issues, socket to short for the U bolt, drop a couple of things which didn't roll off the roof, and so on. The good news is that I didn't fall off the roof.

The bad news that the cable was about one foot short of the splitter under my desk. Back on the roof, eliminated a service loop on the mast (hopefully not to me future regret), re routed the cable to make the run a bit shorter, made a smaller drip loop at the cable entry point. That worked and gave me about two feet of slack at the splitter.

The connector on the inside went on easily. I used a compression F connector instead of a crimp on. Really nice once you get the hang of it.

Once that was all done I turned on the scanners, and started up DSD. On DSD 700, 800, and 900Mhz are measurably stronger, UHF seems more or less the same. I'm going to fool around with that a bit more when I get the chance. I was able to get Site 8 on ICE (Johnston) with no problems where before it was hit or miss.

On the 536HP, 900 and 800 are also better, and UHF seems better. I can get some of the BPD channels I couldn't get before.

The Tram is at least as good as the RS scanner was before it broke, although it's definitely better on 800/900.
