Reviews Summary for MFJ 1899T
MFJ 1899T Reviews: 24 Average rating: 3.1/5 MSRP: $79.95
Description: Yaesu FT-817 Multi-band Telescopic Antenna 6M/10M/12M/15M/17M/20M/30M/40M/80M

Covers 80 Meters through 6 Meters.

This special antenna was designed specifically for the extremely popular Yaesu FT-817 Multimode HF/VHF/UHF Portable Transceiver. This antenna covers all bands (including WARC bands) from 80 Meters to 6 Meters. Power rating is 25 Watts. When fully telescoped it is 1.65M long approximately and is fitted with a BNC connector. This makes it ideal for the new FT-817 or other QRP portable radio. Band changing is achieved by plugging the "wander lead" into the appropriate socket on the base coil, and fine tuning adjustments are made using the 10 section telescopic whip. The whip unscrews from the base matching coil, so collapsed, the antenna measures only 32 cm.
Product is in production.

Ok so far  Time owned: 0 to 3 months
UPS delivered my MFJ-1899T yesterday from Gigaparts and I quickly pressed it into service. So far so good. I have a FT-857D so I turned the RF output down to 20 watts (25w is the max RF output on the 1899T). A counterpoise (CP) is highly recommended for this antenna. I use a 40' CP secured to the body of the 857D. I am wondering if that is the best place to secure the CP on the 857D. Any ideas? The heat sink perhaps?

Last night at 0200 hrs UTC I monitored an interesting QSO between two hams on 80m (I was in my bedroom at the time with the 857D using a 12V/7Amp battery with the 1899T fully extended with no taps, as recommended by manufaturer). Not bad. Indoors? Wow. Now I will try it out-doors on 10 and 20m tomorrow in the AM. Will report on results.

Update to my Sept. 13, 2010 review  Time owned: 0 to 3 months
I thought it important to follow up on my previous review (September 13, 2010) to confirm that this antenna is indeed a practical HF portable antenna for QRP operation.

I have now worked 2 European stations on 20 metre CW from Toronto, Canada using this antenna during a period when HF band conditions are still notoriously poor or mediocre! Not to mention countless QSOs into the southern US.

These were my operating conditions:

- FT 817 at 5 watts with 12v 2.3 aH lead acid battery
- MFJ 1899T connected to rear of MFJ 16010 random wire tuner
- single wire counterpoise hung from tree branch at about 4 feet with alligator clip to radio heatsink (for convenience I use a single reel Yo-Tenna as the counterpoise but any wire will do)

I should add that the base of the MFJ antenna was only 1 foot off the ground when I made these QSOs, far from ideal!

While adding weight to my backpack, the MFJ portable tuner does make tuning much easier and is also a convenient support for the antenna. It also means that the length of the counterpoise is no longer critical.

Yes, you could do better with a dipole but this is so quick and easy to set up that I just can't resist - and it works!

Good dx, folks.

No 17mtr & fragile  Time owned: more than 12 months
This would also apply to the ATX 'Walkabout' antenna sold by W/S & Power Port. I've had mine for about a year. I've used it many times with my FT-817 & others while pedestrian mobile. I broke the telescoping antenna tip & purchased a 75mtr only antenna just get get a new whip. My biggest gripe is the BNC only antenna connection which is too fragile both on the radio & the antenna. I made a goose neck base similar to military antennas from an old desk lamp & this did help.

My second gripe is no 17mtrs(even though the instruction sheet & the propaganda says it does). Tuning is no where near where the instruction sheet says. They could have easily added a 60 mtr tap for a few cents but they didn't, but then, they didn't bother to have separate 20 & 17mtrs taps so..

This antenna will radiate a signal but you must be very careful, & it a bugger to set up. I would buy another one but only if it were thought out a little better. I am amazed at the fact that manufactures build & sell this stuff then keep on selling the exact same thing for years the very same way even though numerous flaws have been brought to their attention.

PORTABLE  Time owned: months
You need an antenna analyzer AND some sort of counterpoise to tune this thing properly. Once this is done it performs according to expectations. does a 1000 mile 20m 10-watt PSK31 QSO into Calgary from the San Francisco Bay Area during a low sunspot year while having the antenna anchored to my bed count as good performance ?. Not bad for a $50 dummy load. Are there better choices than this ?. You bet. I mostly use the antenna for monitoring the HF bands and it's nice to know you can use it for transmit albeit with limitations (the inefficiency and low power restrictions on the lower bands makes it practically unusable) but for 20m and up I bet it's pretty decent. The construction seems fragile especially the BNC connector.

Absolute Garbage!!  Time owned: 3 to 6 months
This piece of trash is built extremely poorly. The center pin on the BNC broke off inside the connector in my FT-817. If I wasn't handy with a soldering iron and small electronics, I would have had to send the rig into Yaesu for repair and who knows what it would have cost me. Oh I also contacted MFJ about this several times and they NEVER returned an email or a phone call. I don't know what is worse their products or their support. What ever happened to their "no matter what guarantee" ? I just threw my $60.00 away. Don't by any MFJ junk. I can safely say that I will never own ANY MFJ garbage ever again. If I could give this thing less than a zero I would!

has potential  Time owned: 3 to 6 months
I had this antenna for 6 months then sold it on EBAY. It has potential, but you need to carry the manual or a cheat sheat with you to find out what tap to use on a certain band then had to adjust the telescoping antenna different for each band. Just a pain in the butt. Once adjusted like the manual says it will work. I made several contacts using a counterpoise. If your looking for doing it on the cheap and do not mind refering to the manual everytime to adjust then go ahead and buy it

Great antenna!  Time owned: 3 to 6 months
My antenna got broken and I tried MFJ's no questions return policy. I only paid minimal shipping and handling ($7.00) and quickly received a brand new antenna. I use it on 80 through 20 meters with good results; it is much easier to use with the Outback Joey tripod, and a PL-259 connector to the rear of the FT-817. It's definitely a keeper and go-with-you- everywhere antenna.

Fantastic QRP Antenna  Time owned: 0 to 3 months
Purchased an MFJ-1899T used for a good price, didn't expect miracles from it, but added it to my QRP gear collection. Over the holiday using my Yaesu FT-817ND and this little antenna on 20 meters I was able to check into the Maritime net. 2.5 Watts output (on the internal battery) I talked to Utopia, ON Canada from central Texas. It's a keeper, and if i ever break this one accidentally, I will buy another to replace it.

Excellent SWL antenna  Time owned: more than 12 months
The MFJ-1899T is an ok TX antenna with a counterpoise, when used with the FT-817. Iíve had some QRP DX with it. And then it sat in the box while the MP-1 did most of the QRP DX work. However, I've found that using the 1899 as an SWL antenna, with these broadbanded HTs such as the Th-F6A and the VX-2, and it is excellent!

Don't tell MFJ  Time owned: 0 to 3 months
Well my FT-897D puts out 20 Watts on internal battery, so why not give it a try. MFJ says the antenna is good for 25 watts. I hurriedly connected it to the radio and gave it a shot inside. Nothing and hard to tune. So the next day was the on the air swap meet day and a lovely day outside. (I have to say that I live in Southern California). This time I added a counterpoise to the ground lug on the radio. I could not believe what I heard and did. SWR was tuneable to flat and signals were strong. Ok it heard, but can any body hear me. After a couple of listing I did my "contact" and net control came right back with a great signal report.

I used a right angle adapter to connect to the coax connector. I just used the internal bar meter of the FT-897D to adjust SWR. The factory setting get you close enough. You just have to use your noggen a little to get the SWR down.

For the FT-817 yes, but it is great for any QRP radio, just don't tell MFJ.
