is this antenna able to transmit above 148 mhz up to 174mhz and 400 mhz to 470mhz ?

Will this antenna work for a 0.5W Long Range (10km) Dual Mode Stereo Broadcast Home FM Transmitter?

I don't know for what frequencies this antenna is actually structurally designed, nor at what frequencies it has been tested. I've never tried it on those frequencies. I often research online at credible electronics engineering websites before making my own purchases. There are also some reliable companies online that specialize in antenna design, manufacture and sale.

Yes, swr will change the more you get out of the bands it was pre-tuned for.

Measured with a relative SWR bridge, I got a very broad range of low swr as follows:140 - 1.5, 150 - 1.7 and 174 - 1.3400 - nil, 444 - 1.1 and 470 1.3I'm unable to test above 470 or below 140 but I suspect the swr would stay below 3.0 for quite aways.It is adjustable (mostly effects VHF).

Sorry, but I cannot answer that question. I returned the antenna as it did not work in my garage to improve reception.

In a word.... YES. However, it works better at or near the HAM frequencies. The stock antennas are OK, the 7 inch are better, and the 15 inch are best.

Hi afhmiami,My straight answer to you is "I do not know", since I have not tested the off the air antenna before with SWM16.The use of AM-21 of the air tuner seems plausible. I hope this helps.Nick.

It is not a question of fit or power the antenna will provide an adequate standing wave ratio over the 10 to 11 meter bands. This is not the proper antenna for transmission on the other frequencies you refer to in your question.

I don't know but I would not recommend this antenna. All of the testing I did with this antenna indicated that it decreased signal range as compared to factory antenna on my wireless access point. I took several measurements in different directions and at varying distances and in all cases the signal strength was less with this antenna.

It sure does. Receives & transmit with no problem. Sounds good both ways. I have two BF 888s and a UV-B6. Plan to get one for my UV-B6 It is for the frequencies of 888s

I've looked at the unit itself. No frequency listing is published anywhere on it. Could be 900 Mhz, could be 2.4 Ghz, no way to know.

From my experience, I would say no. That antenna will cause the output drivers to overload because it will take more power to drive them. This will cause transmission errors.

I do not have the slightest idea. As the antenna mounts within a manufacturers product line are the same there is a possibility of compatibility. Is it matched to the frequency range is anybodies guess. Have you checked the specs?

It depends on the broadcast frequencies used in your country; it works best on the U.S. UHF TV band (470-700MHz), and is somewhat less effective on the VHF-high band (174-216MHz). I don't know about the frequencies between 216 and 470MHz (which are not used for TV in the USA), but it won't work well below 174MHz (channel 7 in the USA).

Larry.......... It is a tough question. Both of them work on the 2.4GhZ range and both have 16 selectable channel. The APUTURE also has a 433 MhZ encrypted. I can honestly say with a 50%-50% certainty assurance........... "YES" Just to be sure give them a call to both manufacturers to ask for more specifications/compatibility with other products/range. The RFN is a great product and does not beet to be in the line of sight to be able to work. Francisco

It is a dual band VHF and UHF FM transceiver. Depends on what "marine frequencies" you want to use and whether they are FM or not. The VHF range is 136mhz to 174mhz, so if the marine frequency you are wanting is within that range, and is FM, then yes.

I'm not certain but I tend to think not..... we also at this time are Not happy with the signal range as I read before we purchased. The company replaced our unit under warrenty with a new unit which was (very nice) but the replacement had another broken antenna? And as the unit fuctions, however it does not extend beyond our previous signal which is basic.

No, you normally need to have a receiver that will send out a signal at 900Mhz. This is old technology, difficult to find.

the range of this transmitter is very good, look I live in a small town in Honduras, about my city is about 5 km, so I have an antenna TYPE: Wave 8.5 Vertical Collinear Antenna FM this is the link of the antenna : 5/8 Wave Collinear Vertical FM Antenna .... I hope you serve the information, if you have other queries you make it
