RF VHF HIGH PASS FILTERS
R.F. FILTER - FILTERS FOR TRANSCEIVERS - FILTERS FOR RECEIVERS FILTERS FOR SCANNERS ETC.

 - The most important type of electromagnetic harassment of transceivers receivers scanners etc today, is what emanates from the very powerful signals emission of F.M. radio and television stations. This harassment is presented in portable and in mobile V.H.F. and U.H.F. radio devices. It usually becomes perceptible from the clue in S-meter of transceiver etc, without however making reception of some station. What happens in this case is that the frond-end of the receiver has blanketing and the receiver cannot make reception not only with weak signals but in a lot of cases still and very powerful. This situation is not as other interferences that happens for few moments and afterwards stops. The radio emissions are possessed on a 24 hour basis therefore also the harassment that creates is continuous.

 - We also faced this problem a while ago. As soon as we put our transceiver with a better external antenna, their receiver was made useless. After a lot of trials, measurements and tedious experiments we eliminated completely the above problem with a HIGH-PASS filter, SV1FJ-01 that we adapted in one very beautiful, small, metal plasticization box with male and female connector, to easily fit between the antenna connector of radio and connector in transmission line of exterior antenna.

 - This filter begins to attenuate all signals from 130 MHz and under. Reaching at 108 MHz has achieved attenuation in the entering signals, the order of 50 db! With this much attenuation in the spectrum of radiofrequencies is also found in radio band of the broadcasting F.M., these stations practically are disappeared by our transceivers even when we go very near them. The power that can pass in from the filter is more than the 50 watt and attenuation that causes this filter in the 2m band (144-148 MHz) and in the 70 cm band (430-450 MHz) is practically negligible (less than 0,5 db) and thus all functions work again beautifully.

 - Today we are in the pleasant place we can to you offer this filter more improved as well as other with different connectors (PL-259, N-TYPE ETC).

All our products are drawn and manufactured with big assiduity and after long-lasting research and experiments. We offer them to you now also after first they helped and resolved our own problems, that is why we are certain that they completely achieve aim for what they are intended to do!

WE WORLDWIDE SHIPPING

How to order
 Make an order only for products that exist in stock. For the rest you will have to wait for a few days until available.
Expenses of shipping you pay for each parcel and not for each product that you will order. Example: if you ask 2,3 products a parcel you will only pay a small difference for each additional piece. This difference is reported in the price of each product, in the expenses of shipping and exists because of weight increase of the parcel.
 We send internationally, after we have been paid first with one of the following ways. If you have you some other secure way you can propose to us.
 In few days will exist a sure way to order with your credit card (VISA or MASTERCARD) ON LINE through our site.

--------------------------------------------------------------------------------

 For ordering something and paying with credit card:

 After you choose the product or the products that you want and know their total price, you add also the sum for the expenses of shipping. Thus it results in a final sum that we will charge your credit card.
 Photocopy the front and the rear side of credit card (VISA or MASTERCARD). This is for we are protected and you from stolen numbers of credit cards.
 On the same paper you write clearly and readably:

 - The products that you want with their code and price. P.h. (1 RF FILTER SV1FJ-02 X 85$ = 85$)
 - The expenses of shipping. E.g. (10$)
 - The total sum. E.g.. (85+10=95$)
 - The name, the surname and the address of delivery.
 - Telephone, Fax or e-mail if they exist (for likely agreement if necessary).
 -
Sign the paper.

 After you are certified that you have written exactly what you want, your address and that they are all readable, send us with FAX this paper to the number:
+30 210 6830030

 Or post us the paper in the address:

 "GALAXY"
 KRITIKOS IOANNIS
 KARAOLI DIMITRIOY 17A
 HALANDRI - 15232
 ATHENS - GREECE

 Or scan to a picture in jpeg format and send us with e-mail as attached file.

 After we receive the FAX, e-mail or the file with the order, the next business day we charge the credit card and make the shipping with post informing you simultaneously with FAX or e-mail for the realization of shipping.

--------------------------------------------------------------------------------

 For ordering something and paying without a credit card:

 Another way that we have used in the past for smaller sums of money (and the transaction has been fulfilled without no problem) is also the following:
 After you choose the product or the products that you want and know their total price, you add also the sum for the expenses of shipping. Thus it results final sum.
 On a piece of paper you write clearly and readably:

 - The products that you want with their code and price adding and the expenses of shipping.
 - The name, the surname and the address of delivery.
 -
Telephone, Fax or e-mail if they exist (for likely agreement if necessary).

 Assemble in cash (attention no coins) the above final sum. Fold with the paper (that you have written the what you want, address and way of communication), the cash and put all together in a dark brown envelope so that the contents of the envelope are not visible . Close and seal the envelope well. Write on the envelope above left your address and then our address:

 "GALAXY"
 KRITIKOS IOANNIS
 KARAOLI DIMITRIOY 17A
 HALANDRI - 15232
 ATHENS - GREECE

 After you are certified that you have written correctly the addresses, mail the letter and the envelope with registered mail.

 After we receive the envelope with the order, the next business day we make the shipping by post informing you simultaneously with FAX or e-mail for the realization of shipping.
