I have about 100 50 ohm SMA loads that were used by Motorola on a Nextel receiver multi-coupler. They were used to terminate unused ports on the multi-coupler. A test with a network analyzer shows tha

Warren, I think I stated that. "So a 100 watt station will give you 88.9 watts of ERP (Less cable loss and plus antenna gain)." So, I accounted for the fact that there would be cable loss and it would

WHAT?? All that power being lost???? Seriously, a 2:1 SWR will only loose 11.1% of the power. So a 100 watt station will give you 88.9 watts of ERP (Less cable loss and plus antenna gain). Really not

I agree. I've been a ham now for over 65 years. When I was a kid we just put up a dipole and got on the air. After that, we realized what a marginal or bad antenna was and worked on improving it. But,

I agree. Don't try to save a $1 and get a $40 headache. There are other sources that are also just as reliable, but it's nice to have a stateside telephone number to call and a live person to talk to.

Mike, You still may have a few years left. We used to hire Ray Mercier from Waterford CT to do our climbing. I've seen him climb to 200 feet (rest for a few minutes every 50 feet). I had heard that he

The first step that I would do is look at the label and see if it notes the original frequencies that the duplexer was built for. Hopefully, it is within the tuning range of what you want. Second woul

I went to order a TINYSAULTRA from R&L Electronics and I see that they are out of stock. Is there any other reputable dealer/store that would be a good place to order from? Thanks ahead of time, Joe,

The other advantage is that some VNA's like the Anritsu Sitemaster and Cellmaster can overcome some interference. My Anritsu can send a coded signal that it can use to ignore the interference. If the

I was just trying to point out that if you have a choice between using a short or open on any device, the short would minimize or eliminate interference that might enter the end of the cable. Joe

I do fault locating with the Anritsu SiteMaster and the CellMaster. I prefer to use a short when testing because it seals off the end of the cable and avoids/reduces interference. This can help when t

This is where the professional devices excel. I have an Anritsu SiteMaster and a CellMaster that have the capability of ignoring these extraneous signals. The Anritsu devices send a coded signal up th

What do you have the ham stick mounted on/ Joe, k1ike

I would insulate one end for safety and connect AC to the other side. I would then use my AC probe tester (the kind you hold near an AC outlet to see if it is hot) and slide down the wire until the in

22 messages about this so far...... To the author of the guide, thank you for taking the time and making the effort to share your information. Any format is OK with me. Now I will take a couple of min

Zack, What about speeding up the heating process by using a heat gun and very gently warming the ferrite rod from a distance? This might prove that the change may be caused by heat. Joe, K1ike

They even came on steroids. Joe

How about connecting an antenna tuner between the FM radio and the antenna? Tune he ATU for maximum received signal. Then, replace the FM radio with the NANOVNA and read what the impedance is. This sh

I used crystal filters on a 72-75MHz paging repeater years ago and found that they were lossy and drifted over time. They were very sharp and solved our problem. Loss was not a problem as we were deal

Hello to All, This story points out something that I have been trying to point out for years. Many of us have been trying to get youngsters to get their tickets and get on the air. This is important,
