N elbow connector problem with FT-817.

straight up when the radio is on a table with speaker firing upward. The connector when onto the FT-817 fine, but the rubber duck will not for the life of me go onto the other end of the elbow. Paid $5.00 for this one; thought it was good. Am I doing something wrong or is the tolerance of this antenna too tight for anything but the most on-spec elbow? Anyone else have this problem?

It is *very* easy to calibrate. Has a calibration procedure/capabailaity built into the unit. You adjust a pot for a specified voltage & three more pots for a fixed output reading. Very easy...takes about two minutes. The unit is well designed and appears to be quite accurate on all three reading scales. (10W, 1W, 100mW) The LDG digital wattmeter looks interesting also!

Are you talking aout an N connector or a BNC connector?

I'm curious, since the connector on the rear of the radio is a "UHF" (SO239), and since I have never seen an elbow that has a plug to match that on one end and a BNC on the other side, what is the actual configuration you're using? Do you have a UHF elbow and then a UHF to BNC adapter? BNC's will generally fit without problems. The most common reason when they don't is that the connector has been squished and is now slightly out-of-round. If that's the case, you may be able to fix it by carefully reshaping the connector. Since the antenna still plugs into the front connector on the radio, it's would most likely be your adapter (assuming you do have the right connector on the adapter.

Jeffrey,
I have a box full of BNC adapters including male-to-male elbows, female-to-male elbows, barrel connectors...you get the idea. And I can tell you that often times one BNC does not match another BNC in the world of adapters. Sometimes the center pins on the BNC adapters are thicker than others. This creates a problem trying to get the antenna end of the BNC to push down, twist and lock on to the radio end. In fact, I have found this to be the case on my 817, but I don't know if it is an 817 problem or an adapter problem to be honest. The ducky works just fine. And the Maldol whip I have works just fine, but the Maldol does seem to resist locking into place, although it does after a bit of effort. I have a BNC elbow on the front of the radio now as the rig sits on my desk and the elbow does NOT lock onto the radio like it should. I can not get it to fully twist and lock. I have a VHF/UHF vertical in my yard that I'm using with this configuration. Another post suggested that your connector might have gotten tweaked out of shape. That certainly is another possibility, but if you just bought the elbow it should be shaped OK...doesn't mean it isn't but you'd think something new would not be bent. Try the elbow on other devices you have with BNC's on them and see if it works OK. If it does, then maybe we have some type of issue with the 817 connector since I too have experienced some resistance to twisting and locking on BNC's to the rig. Has anyone else had problems like this?

fine. These are available from just about anyone who sells wire/cable. Not sure if RS has them but their connectors are usually pretty poor. Connectors one place to stay with a name brand and if they cost a few cents more they're worth it. ----- 73, Rich - W3ZJ www.w3zj.com -----Original Message-----

BE very careful with BNC's. There are 75 ohm as well as 50ohm BNC's
out there. The difference is the center conductor. One is thicker than the other. In one configuration the connection will not be good and the other you could damage the center pin. Someone else with more knowledge should tell us which impedance is the thick one. There were some earlier postings about the BNC problem on the front of the 817.

Hi Jeffrey,
Your main problem is neither connector on the 817 is a type N. The front is a BNC & the rear is a UHF (SO-239). No one I know of makes an elbow adapter from UHF (SO239) to BNC. You can buy BNC M-F elbows all day. so use the front BNC connector for the antenna. 73, Fil W8FIL Jeffrey Steinberg wrote: I bought an N connector elbow so that when I use the rubber duck, it[YAHOO!

it works OK. If it does, then maybe we have some type of issue with
the 817 connector since I too have experienced some resistance to Yes, the FT-817 front panel has a clearance problem with many BNC plugs. They do not seat fully. Do NOT force the plug on, you will strain the ears on the socket. Rather, remove the front panel ( easier than it sounds ) and ream out the front panel hole. Seethe FAQ link below.

the other is 75 ohms. The smaller diameter is 75 ohms.
